Photonic THz transmitters have so far remained below 350 GHz because high-frequency photomixing suffers from phase noise and power limits. Here we demonstrate single-channel wireless transmission at 560 GHz using a fibre-packaged silicon-nitride soliton microcomb as a compact, low-phase-noise optical reference. A high numerical aperture, UV-bonded fibre interface sustains soliton operation for more than 24 hours with 1 W pump power. We phase-lock two distributed-feedback lasers (DFBs) to adjacent comb lines and photomix them in a uni-traveling-carrier photodiode, generating a 560 GHz carrier that bears in-phase and quadrature modulation. We achieve hard-decision forward-error-correction-qualified quadrature phase-shift keying and 16-quadrature amplitude modulation (16QAM) transmissions at 42 and 28 GBaud, respectively, attaining a record 112 Gbps data rate at 560 GHz. Relative to free-running DFBs, microcomb-locked photomixing cuts carrier linewidth and improves 16QAM error-vector magnitude. The results establish soliton microcombs as compact and scalable frequency references for &gt;100 Gbps sub-THz links and chart a path toward compact 6 G back-haul radios.

The scheme employs dual-wavelength optical carriers referenced to a soliton microcomb and performs THz-to-optical carrier conversion via nonpolarimetric electro-optic downconversion using an electro-optic polymer modulator. RF spectra and eye diagrams confirmed error-free transmission with a Q-factor of 5.78 and a bit-error rate of 3.74 × 10 ^-9 , well below the hard-decision forward-error-correction threshold (Q-factor = 2.67, (BER) = 3.8 × 10 ^-3 ). Comparative measurements using a single-wavelength optical-carrier configuration clearly revealed the superior signal-to-noise performance of the dual-wavelength scheme. System-level modeling further indicated the scalability of the transmission distance beyond 100 m. These results establish soliton microcomb-referenced dual carriers as a promising platform for compact, integrated receivers enabling seamless wireless-optical convergence in future 6G networks.

This study presents a novel approach to wireless data transmission at 560 GHz, leveraging the use of THz waves generated through the injection-locking of a pair of distributed feedback lasers into a Kerr micro-resonator soliton comb. Experimental results demonstrate a Q-factor of 6.23 in 1-Gbit/s on-off-keying data transmission, which closely approaches the error-free limit represented by a Q-factor of 6.36. Additionally, the study achieves low error vector magnitudes for various modulation formats: 23.9% for 1-GBaud binary-phase-shift-keying, 23.6% for 1-GBaud quadrature-phase-shift-keying, and 8.07% for 0.1-GBaud 16-quadrature-amplitude modulation. This innovative approach holds promise for achieving high-quality, high-speed wireless data transmission, thereby advancing THz communication technology for integration into 6G systems.

Liver fibrosis is assessed mainly by conventional staining or second harmonic generation (SHG) microscopy, which can only provide collagen content in fibrotic area. We propose to use polarization-resolved SHG (PR-SHG) microscopy to quantify liver fibrosis in terms of collagen fiber orientation and crystallization. Liver samples obtained from autopsy cases with fibrosis stage of F0-F4 were evaluated with an SHG microscope, and 12 consecutive PR-SHG images were acquired while changing the polarization azimuth angle of the irradiated laser from 0° to 165° in 15° increments using polarizer. The fiber orientation angle (φ) and degree (ϱ) of collagen were estimated from the images. The SHG-positive area increased as the fibrosis stage progressed, which was well consistent with Sirius Red staining. The value of φ was random regardless of fibrosis stage. The mean value of ϱ (ϱ-mean), which represents collagen fiber crystallinity, varied more as fibrosis progressed to stage F3, and converged to a significantly higher value in F4 than in other stages. Spatial dispersion of ϱ (ϱ-entropy) also showed increased variation in the stage F3 and decreased variation in the stage F4. It was shown that PR-SHG could provide new information on the properties of collagen fibers in human liver fibrosis.

For example, testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is essential in the fight against the coronavirus disease 2019 (COVID-19) pandemic. Reverse-transcription polymerase chain reaction (RT-PCR) is the current standard for COVID-19 testing; however, it is hampered by the long testing process. Simplifying and shortening the testing process while achieving its high sensitivity would facilitate sooner quarantine and thus presumably prevent the spread of SARS-CoV-2. Here, we aim to achieve the rapid and sensitive detection of SARS-CoV-2 by enhancing the performance of optical biosensing. We demonstrate optical biosensing based on a dual configuration of optical frequency combs (OFCs), enabling detection of the SARS-CoV-2 nucleocapsid protein. The virus-concentration-dependent optical spectrum shift produced by antigen-antibody interactions is transformed into a photonic radio-frequency (RF) shift by a frequency conversion between the optical and RF regions in the OFC, facilitating rapid and sensitive detection with mature electrical frequency measurements. Furthermore, active-dummy temperature-drift compensation with a dual-comb configuration enables the very small change in the virus-concentration-dependent signal to be extracted from the large, variable background signal caused by temperature disturbance. This dual-comb biosensing technique has the potential to reduce COVID-19 testing time to 10 min, which is considerably shorter than RT-PCR, while maintaining sensitivity close to that of RT-PCR. Furthermore, this system can be applied for sensing of not only viruses but also various biomolecules for medical care, food inspection, and environmental monitoring.

Herein, we integrated angle-scanning surface plasmon resonance (SPR) and angle-fixed SPR as a hybrid angular-interrogation SPR to enhance the sensing performance. Galvanometer-mirror-based beam angle scanning achieves a 100-Hz acquisition rate of both the angular SPR reflectance spectrum and the angle-fixed SPR reflectance, whereas the use of near-infrared light enhances the refractive index (RI) sensitivity, range, and precision compared with visible light. Simultaneous measurement of the angular SPR reflectance spectrum and angle-fixed SPR reflectance boosts the RI change range, RI resolution, and RI accuracy to 10-1-10-6 RIU, 2.24 × 10-6 RIU, and 5.22 × 10-6 RIU, respectively. The proposed hybrid SPR is a powerful tool for wide-dynamic-range RI sensing with various applications.

Although most of them report on the coupling between the electric field and the electric dipole, the coupling between the magnetic field and the magnetic dipole is rarely reported. In this study, we investigated the strong coupling interaction between a magnetic field and a magnetic dipole using a Fabry–Pérot microcavity structure in the THz region consisting of wire grid (WG) mirrors and rectangular hole (RH) metamaterials. Here, the RH is well known as a magnetic current type slot antenna, which can be regarded as a magnetic dipole. To verify this concept, we analyzed the transmission properties of WG, RH, and a microcavity consisting of WG and RH (WGRH) using the transmission line theory. Consequently, we found that in this WGRH, normal mode splitting occurs, and anti-crossing behavior is observed in the dispersion relation. The samples were designed using the finite difference time-domain method and were fabricated via photolithography. We measured the transmission spectrum of the fabricated samples using THz time-domain spectroscopy. Finally, we observed a splitting of the transmission peak owing to mode coupling between the magnetic field and the magnetic dipole in WGRH.

Photonics-based techniques, in which optical two tones are translated to a THz wave through opto-electronic conversion, are promising if the relative phase noise between the two tones is well suppressed. Here, a THz (≈560 GHz) wave with a low phase noise is provided by a frequency-stabilized, dissipative Kerr microresonator soliton comb. The repetition frequency of the comb is stabilized to a long fiber in a two-wavelength delayed self-heterodyne interferometer, significantly reducing the phase noise of the THz wave. A measurement technique to characterize the phase noise of the THz wave beyond the limit of a frequency-multiplied microwave is also demonstrated, showing the superior phase noise of the THz wave to any other photonic THz oscillators (&gt;300 GHz).

Additionally, we measured the nucleocapsid protein antigen of SARS-CoV-2 down to a molar concentration of 1 fM by immobilizing its corresponding antibody on the SPR sensor surface.

Dual-comb microscopy (DCM), based on a combination of dual-comb spectroscopy (DCS) with two-dimensional spectral encoding (2D-SE), is a promising method for scan-less confocal laser microscopy giving an amplitude and phase image contrast with the confocality. However, signal loss in a 2D-SE optical system hampers increase in image acquisition rate due to decreased signal-to-noise ratio. In this article, we demonstrated optical image amplification in DCM with an erbium-doped fiber amplifier (EDFA). Combined use of the image-encoded DCS interferogram and the EDFA benefits from not only the batch amplification of amplitude and phase images but also significant rejection of amplified spontaneous emission (ASE) background. Effectiveness of the optical-image-amplified DCM is highlighted in the single-shot quantitative nanometer-order surface topography and the real-time movie of polystyrene beads dynamics under water convection. The proposed method will be a powerful tool for real-time observation of surface topography and fast dynamic phenomena.

The PS-THz-DH enables us to separate the necessary diffraction-order image from unnecessary diffraction-order images without the need for spatial Fourier filtering, leading to suppress the decrease of spatial resolution. 3D shape of a visibly opaque object is visualized with a sub-millimeter lateral resolution and a sub-µm axial resolution. Also, the digital focusing of amplitude image enables the visualization of internal structure with the millimeter-order axial selectivity. Furthermore, the internal stress distribution of an externally compressed object is visualized from the phase image. The demonstrated results imply a possibility for non-destructive inspection of visibly opaque non-metal materials. Opt.

Due to its specific collagen selectivity without staining, non-invasiveness, and high-resolution 3D imaging capability, collagen fiber structure can be visualized as high-contrast SHG image <i>in situ</i>. However, it is difficult to extract quantitative parameters reflecting the collagen fiber structure from SHG image. Also, its practical use is limited in the dermatological field due to its bulky and complicated setup. In this review paper, we first review the application of the two-dimensional auto-correlation analysis for SHG image of the dermal collagen fibers in the human cheek skin. The extracted index for the collagen fiber structure significantly decreased with aging. Furthermore, we confirmed the moderate correlation between the collagen fiber structure index and the skin elasticity measured by Cutometer^®. This correlation indicated that the dermal collagen fiber structure play an important role to determine the skin elasticity. In other words, the auto-correlation analysis of SHG image can be used for evaluation of the skin elasticity from the viewpoint of the dermal collagen. We next review the construction of a photonic-crystal-fiber (PCF)-coupled, hand-held SHG microscope for <i>in situ</i> monitoring of collagen fibers in human skin. While the ultrashort pulse light is delivered from a laser source to the SHG microscope <i>via</i> a large mode area PCF, SHG microscope was enclosed into a hand-held probe head. We compare the imaging performance between the conventional SHG microscope and the hand-held SHG microscope, and confirmed the comparable performance to each other. Finally, we demonstrated <i>in situ</i> visualization of collagen fibers in human skin. The combination of quantitative texture analysis with the hand-held SHG microscope will move SHG microscopy closer to the clinical applications in fields of skin cosmetics and anti-aging dermatology.</p> Japanese Cosmetic Science Society 日本香粧品学会 JOURNAL OF JAPANESE COSMETIC SCIENCE SOCIETY 日本香粧品学会誌 1880-2532 43 1 18 23 20190000 10.11469/koshohin.43.18 read0191176/published_papers/29514872 KAMEYAMA Yuta 亀山 結太 IKI Yosuke 伊岐 陽佑 MATSUMOTO Takeshi 松本 健志 MINAMIKAWA Takeo 南川 丈夫 YASUI Takeshi 安井 武史 SATO Katsuya 佐藤 克也 Effects of microvibration stimulation with resting phase on osteoblastc matrix production 休止期を挿入した微振動刺激が骨芽細胞のマトリックス産生に及ぼす影響 The Japan Society of Mechanical Engineers 一般社団法人 日本機械学会 The Proceedings of the JSME Conference on Frontiers in Bioengineering バイオフロンティア講演会講演論文集 2019 0 2A31 null 20190000 10.1299/jsmebiofro.2019.30.2A31 read0191176/published_papers/29514870 SATO Katsuya 佐藤 克也 OKAZAWA Shota 岡澤 章汰 KAMEYAMA Yuta 亀山 結太 MATSUMOTO Takeshi 松本 健志 MINAMIKAWA Takeo 南川 丈夫 YASUI Takeshi 安井 武史 Enhancement of osteoblastic matrix synthesis by using mechanical vibration stimuli 微振動刺激による骨芽細胞のマトリクス産生促進 The Japan Society of Mechanical Engineers 一般社団法人 日本機械学会 The Proceedings of the Bioengineering Conference Annual Meeting of BED/JSME バイオエンジニアリング講演会講演論文集 2019 0 1F31 null 20190000 10.1299/jsmebio.2019.31.1F31 read0191176/published_papers/27768456 Oe, Ryo Oe Ryo Minamikawa, Takeo Minamikawa Takeo Taue, Shuji Taue Shuji Fukano, Hideki Fukano Hideki Nakajima, Yoshiaki Nakajima Yoshiaki Minoshima, Kaoru Minoshima Kaoru Yasui, Takeshi Yasui Takeshi Simultaneous measurement of concentration and temperature in liquid sample using multi-mode interference fiber comb OPTICAL FIBERS AND SENSORS FOR MEDICAL DIAGNOSTICS AND TREATMENT APPLICATIONS XIX 1996-756X 10872 null null 20190000 10.1117/12.2509539 read0191176/published_papers/14049073 Eiji Hase Takeo Minamikawa Shuji Miyamoto Yasuhiro Mizutani Tetsuo Iwata Hirotsugu Yamamoto Takeshi Yasui Application of Scan-less Two-Dimensional Confocal Microscopy Based on a Combination of Confocal Slit With Wavelength/Space Conversion Confocal laser microscope (CLM) has been widely used in the fields of non-contact surface topography, biomed- ical imaging, and other applications, as confocality gives two- dimensional (2-D) optical-sectioning or three-dimensional (3-D) imaging capability with depth selectivity. The combination of line- focused CLM with one-dimensional spectral encoding CLM en- ables us to obtain the 2-D confocal image without the need for mechanical scanning. The so-called scan-less 2-D CLM is a unique imaging modality; however, there have been no attempts to apply this to practical applications. In this paper, we have constructed a scan-less 2-D CLM with an image acquisition time of 0.23 ms, lateral resolution of 1.2 μm, depth resolution of 2.4 μm, and have applied it to different kinds of applications to evaluate its practical potential.

The DCSE provides fast ellipsometric evaluation with high-spectral accuracy and resolution, wide spectral bandwidth and without any mechanical movements for both the polarization analysis and spectral decoding, which has a big leap in performance of spectroscopic ellipsometry.

In previous studies, histological staining and tensile testing have been widely used to evaluate histological and mechanical healing. However, since both methods are destructive and invasive, it is difficult to apply these methods to clinical diagnosis. If the degree of healing can be visualized nondestructively and noninvasively, new findings may be obtained regarding mechanisms of the tendon healing process. In this study, we used second-harmonic-generation (SHG) microscopy to evaluate the degree of healing of ruptured tendon in a rabbit model. SHG microscopy has high selectivity and high image contrast with respect to the structural maturity, density, and aggregates of collagen molecule, without the need for histological sectioning and staining. Furthermore, since SHG light intensity sensitively reflects the structural maturity of collagen molecule and its aggregates, it has the potential to be a good indicator for the degree of healing of the injured tendon. By comparing the SHG images between 4-week-healing tendons and normal tendons in the animal model, we confirmed that SHG light intensity of the healing tendon was significantly lower than that of the normal tendon, indicating that the collagen structure in the healing tendon is still immature. Furthermore, we performed image analysis based on 2D Fourier transform of the acquired SHG images, and confirmed a significant difference in collagen distribution depending on the sample. These results indicate that SHG microscopy has the unique potential as an indicator of tendon healing.</p> Japanese Society for Medical and Biological Engineering 公益社団法人 日本生体医工学会 Transactions of Japanese Society for Medical and Biological Engineering 生体医工学 1347-443X 54 6 253 260 20160000 10.11239/jsmbe.54.253 read0191176/published_papers/29514824 Yasui Takeshi 安井 武史 Miyamoto Shuji 宮本 周治 Hase Eiji 長谷 栄治 Minamikawa Takeo 南川 丈夫 Mizutani Yasuhiro 水谷 康弘 Yamamoto Hirotsugu 山本 裕紹 Scan-less confocal laser microscopy by a combination of confocal slit with wavelength/space conversion 共焦点スリットと波長/空間変換を用いたスキャンレス・フルフィールド共焦点レーザー顕微鏡の開発 Confocal laser microscopy (CLM) is the imaging modality widely used for 3D shape measurement in the field of industrial inspection. Recently, further reduction of image acquisition time is strongly required for rapid inspection. The conventional CLM has acquired the 2D image by mechanical scanning of the focused beam spot. However, if the confocal 2D image can be obtained without the need for the mechanical scanning, the image acquisition time will be largely reduced. In this paper, we developed the full-field CLM without the need for mechanical scanning of the focused beam spot. By combination of wavelength/1D-space conversion with line-imaging configuration, the broadband light is focused onto a sample as 2D illumination with an objective lens, in which vertical and horizontal coordinate are related with the line image and the spectral wavelength, respectively. After superimposing the 2D image of the sample onto 2D illumination, the spectral line image of the reflected beam was measured by a multichannel spectrometer equipped with 2D CCD camera. The resulting spectral line image directly reflects the confocal 2D image of sample. 共焦点レーザー顕微鏡(CLM)は，3次元形状測定手法として，産業分野で広く使われている．通常，光源側ピンホール・サンプル焦点・検出側ピンホールが共役な関係であるため，イメージを取得するには焦点位置を，機械的に走査する必要があった．本講演では，共焦点スリット型CLMにおいて，共焦点スリットと直交方向に波長/空間変換を導入することにより，スキャンレスで共焦点2次元イメージを取得可能なCLMを報告する． The Japan Society for Precision Engineering 公益社団法人 精密工学会 Proceedings of JSPE Semestrial Meeting 精密工学会学術講演会講演論文集 2016 0 1015 1016 20160000 10.11522/pscjspe.2016S.0_1015 read0191176/published_papers/29514821 Minamikawa Takeo 南川 丈夫 Ogura Takashi 小倉 隆志 Masuoka Takashi 増岡 孝 Nakajima Yoshiaki 中嶋 善晶 Yamaoka Yoshihisa 山岡 禎久 Minoshima Kaoru 美濃島 薫 Yasui Takeshi 安井 武史 Strain sensing with fiber-based optical-frequency-comb cavity ファイバー光コム共振器によるひずみセンシング In this paper, we proposed a novel strain sensor employing optical-frequency-comb cavity. The strain sensing was realized by strain/radio-frequency conversion in a fiber-based optical frequency comb cavity. The fiber-based optical frequency comb cavity generated a repetitive pulse train of which the repetition rate was determined by the cavity length. The application of mechanical strain onto the cavity produced the extension or compression of the cavity length, resulting the change of repetition rate of the pulse train. The resultant strain can be detected by observing the change of repetition rate of the pulse train with a frequency analyzer. For a proof-of-principle demonstration, we constructed an Er-doped fiber-based optical frequency comb system for the strain sensing. We demonstrated static and dynamic strain sensing with the developed system, and realized the strain sensitivity of 84.5 nϵ in the static strain sensing and that of 15 nϵ in the dynamic strain sensing with 2 m sensing fiber length. Our results demonstrated the efficacy of the strain sensor employing the optical-frequency-comb cavity. 本研究では，ファイバー光コム共振器独自の共振器長/周波数変換機能に着目した新しいひずみセンシング手法の開発を行い，静的ひずみおよび数 kHz の時間的変動を持つひずみの計測を行った．その結果，測定ファイバー長を2mとした場合，静的ひずみにではひずみ感度 84.5 nϵ，動的ひずみではひずみ感度15 nϵを実現することに成功した．このことから，本手法による動的/静的ひずみ計測の有用性を示した.

The scan-less confocal microscopy was realized by employing a wavelength/space dimensional conversion of optical-frequency-comb, in which the spatial information was encoded to the individual comb mode by using two-dimensional dispersers. To decode the spatial information using the encoded optical-frequency-comb spectrum, we performed dual-optical-frequency-comb spectroscopy. We constructed a scan-less confocal microscopy system employing a diffractive grating and a virtually imaged phased array as two-dimensional disperser, and provided a proof-of-principle demonstration of the proposed method. 光コムは，高い波長確度を有する膨大な数の光周波数モード群である．本研究では，高い波長分解能で光コムの各光周波数モードの光強度と位相を計測可能なデュアル光コム分光法と，2次元波長分散素子を活用した空間情報を光コムの各光周波数モードに対応付ける波長/空間次元変換法を融合することで，ビームスキャン機構を有さずに2次元深さ分解イメージングが取得可能な新たなスキャンレス共焦点光学顕微鏡を実現した． The Japan Society for Precision Engineering 公益社団法人 精密工学会 Proceedings of JSPE Semestrial Meeting 精密工学会学術講演会講演論文集 2016 0 39 40 20160000 10.11522/pscjspe.2016A.0_39 read0191176/published_papers/17837408 Sho Okubo Yi-Da Hsieh Hajime Inaba Atsushi Onae Mamoru Hashimoto Takeshi Yasui Near-infrared broadband dual-frequency-comb spectroscopy with a resolution beyond the Fourier limit determined by the observation time window OPTICS EXPRESS 1094-4087 23 26 33184 33193 20151200 10.1364/OE.23.033184 26831986 2-s2.0-84961807055 read0191176/published_papers/17837409 Takeshi Yasui Ryuji Ichikawa Yi-Da Hsieh Kenta Hayashi Harsono Cahyadi Francis Hindle Yoshiyuki Sakaguchi Tetsuo Iwata Yasuhiro Mizutani Hirotsugu Yamamoto Kaoru Minoshima Hajime Inaba Adaptive sampling dual terahertz comb spectroscopy using dual free-running femtosecond lasers SCIENTIFIC REPORTS 2045-2322 5 10786 null 20150600 10.1038/srep10786 26035687 2-s2.0-84934883052 read0191176/published_papers/4251926 Takeshi Yasui Yuki Iyonaga Yi-Da Hsieh Yoshiyuki Sakaguchi Francis Hindle Shuko Yokoyama Tsutomu Araki Mamoru Hashimoto Super-resolution discrete Fourier transform spectroscopy beyond time-window size limitation using precisely periodic pulsed radiation OPTICA 2334-2536 2 5 460 467 20150500 10.1364/OPTICA.2.000460 2-s2.0-84941074306 read0191176/published_papers/17837410 Takeshi Yasui Kenta Hayashi Ryuji Ichikawa Harsono Cahyadi Yi-Da Hsieh Yasuhiro Mizutani Hirotsugu Yamamoto Tetsuo Iwata Hajime Inaba Kaoru Minoshima Real-time absolute frequency measurement of continuous-wave terahertz radiation based on dual terahertz combs of photocarriers with different frequency spacings OPTICS EXPRESS 1094-4087 23 9 11367 11377 20150500 10.1364/OE.23.011367 25969231 2-s2.0-84943378238 read0191176/published_papers/47088332 Dahi Ghareab Abdelsalam Hirotsugu Yamamoto Takeshi Yasui High contrast digital holographic microscopy by use of femtosecond pulse light OSA - The Optical Society Optics InfoBase Conference Papers 2019 null null 20150000 2-s2.0-85077187770 read0191176/published_papers/29637925 Takeshi Yasui Eiji Hase Ryosuke Tanaka Shu-Ichiro Fukushima Tsutomu Araki In situ visualization of dermal collagen dynamics during skin burn healing using second-harmonic-generation microscopy SPIE Progress in Biomedical Optics and Imaging - Proceedings of SPIE 1605-7422 9531 null null 20150000 10.1117/12.2180895 2-s2.0-84938944863 read0191176/published_papers/29634509 Eiji Hase Katsuya Sato Takeshi Yasui In vivo visualization of collagen fiber produced by cultured osteoblasts using sensitive second-harmonic-generation microscopy equipped with a 10-fs mode-locked Ti:sapphire laser SPIE Progress in Biomedical Optics and Imaging - Proceedings of SPIE 1605-7422 9329 null null 20150000 10.1117/12.2079114 2-s2.0-84932117224 read0191176/published_papers/28353075 E.

An effective, optical probe method to investigate dermal collagen in vivo is a second-harmonic-generation (SHG) light induced by nonlinear optical property of collagen molecule. In this study, we demonstrated in vivo SHG imaging of dermal collagen fiber in human forearm skin using a mode-locked Cr: Forsterite laser with a center wavelength of 1250nm. The structural difference of dermal collagen fiber is observed along the depth direction. In vivo SHG imaging technique will be a powerful tool for the skin cosmetic and diagnostics.

The proposed method does not require mechanical scanning elements for time delay and sample position, which are essential for conventional THz tomography. For this purpose, a 2D spatiotemporal THz image is acquired at a frame rate of 10frame/s by a combination of electro-optical time-to-space conversion and line focusing of a THz beam on a sample. We demonstrate the use of real-time 2D THz tomography for real-time monitoring of the paint thickness in a moving paint sample and the drying progress in a wet paint film. The proposed method provides a powerful tool for non-ionizing and non-contact probing in the fields of nondestructive testing and biomedical diagnostics.

AGEs (advanced glycation endproducts), which are a crosslink of collagen, are considered to be involved in the mechanisms that cause the fluorescence characteristics to change. Although fluorescence intensity is a well-examined index of aging, it has inherent limitations. In contrast, fluorescence lifetime is useful for the evaluation because it can be reviewed quantitatively. Therefore, we mapped the distribution of fluorescence lifetime of teeth in relation to the formation and aging of teeth. The fluorescence decay profile of teeth was measured by time-correlated single photon counting, and lifetime was calculated from the fitting curve of the decay profile in a two-component exponential function. As a result, the distribution of fluorescent lifetime in dentin corresponded to tooth development; fluorescent lifetime of the crown dentin was shorter than that of the root dentin. Furthermore, the fluorescence lifetime decreased as human age increased. Because these changes in fluorescent lifetime are attributed to the accumulation of AGEs, whose fluorescence lifetime is short, our mapping of fluorescent life visualizes the formation and aging of teeth.

Thereby we observed remodeling of collagen gel, in which fibroblasts were embedded or on which endothelial cells (ECs) were cultured. The intensity of SHG light from a fibroblast-embedded gel progressively increased during 7-day culture. In a gel cultured with ECs, SHG intensity markedly increased until day 2, and then the increasing rate of SHG light was decreased. The observation that high SHG intensity area was associated to cell location indicates that the change of SHG intensity was due to interaction between cells and collagen. Because the quantity of collagen produced by cells was insignificant, mechanical interaction is probably major factor.

A specific probing ability for collagen results from the use of second-harmonic-generation (SHG) light induced by collagen molecules in the tissue. Based on the concept of tissue SHG light, a reflection-type polarization measurement system (named SHG polarimetry) with a probe light spot of 10μm in diameter has been constructed, and human dermis has been measured using this system. Resultant data exhibits that the dermis possesses approximately uniaxial orientation of collagen fibers. Furthermore, we have extended the SHG polarimetry to two-dimensional measurement. By the two-dimensional SHG polarimetry, we have observed a tangled structure of collagen fibers, which is highly consistent with the result of anatomical examination of the skin. The proposed method will be a powerful diagnostic tool for monitoring the structural change of collagen fibers in dermis.

In the present system, yeast cell stained with fluorescence dye was applied as the sensor cell. Fluorescence intensity of the probe cell changes according to the change of cellar environment. To confirm the performance of the proposed CES system, the pollutant (Hg^<2+>) and the biological substance (acetylcholine) were applied. Fluorescence intensity of Rhodamine123 (membrane potential sensitive dye for mitochondria), decreased gradually due to effect of the pollutant, while that of Fluo-3 (calcium sensitive dye) increased.

However, it has not been clearly understood that how do mechanical stimulus affects osteoblasts collagen production. In this study, we applied cyclic stretch strain to osteoblasts as the mechanical stimulus and evaluated an amount of collagen production by using SHG microscopy. The SHG microscopy methods can observe the collagen at living cell in situ, whereas the conventional staining methods require permeabilization and fixation. As a result, we found that the amount of collagen produced by osteoblasts was increased by the cycle stretch strain application.

However, conventional SHG microscopy equipped with a 100-fs laser can not visualize specific samples such as low-order-structured, immature collagen produced by cultured cell because of considerably weak SHG light. One possible method to visualize such the sample is to use a fs laser with shorter pulses because of enhanceed optical nonlinear effect. Based on this idea, we constructed sensitive SHG microscopy equipped with a 10-fs Ti:Sapphire laser and applied it for visualizing collagen fiber produced by osteoblasts. Precise dispersion compensation based on combination of a negative chirp mirror with a positive wedge prism enables us to maintain the pulse duration of 20 fs at the focal point even after passing through a thick objective lens. As a result, we successfully visualized the distribution of low-order-structured collagen produced by osteoblasts.

However, the current speed of image acquisition is relatively low, making it difficult to use it on moving objects. In this paper, We proposed a fast terahertz color scanner based on electro-optical time-to-space conversion and linefocusing of a terahertz beam. The proposed system functions as a color scanner in the terahertz spectral region with fast line-scanning and can be used to image objects, which are moved on a translation stage. We evaluated basic performance of the developed system.

Previously, depending on the type of substrate, various film thickness meters, based on electromagnetic induction, eddy-current, or ultrasound, have been widely used. However, all of them are contact thickness meter, so it was difficult to use them on moving or wet films. To solve this limitation, we focused on free-space-propagating, pulsed THz radiation. In this paper, we demonstrated non-contact, remote thickness measurement of the paint film based on time-resolved measurement of THz pulse echo. The thickness resolution of 23 μm and precision of 8 |am were achieved.
