    We have studied an optical system, which can performs a single-shot phase measurement in the 40 ps time domain by 25 GHz sampling between modes of the 200 GHz optical frequency comb. In case to apply this technology to transient response measurement, wideband and high-resolution phase spectrum measurement and control technology are required to achieve both time resolution and wide time window. A time parallel measurement system has been devised to enable the phase spectrum measurement to be obtained by a phase detection circuit. The amplitude and phase spectra were measured at 375 GHz (25 GHz, 15 modes), and it was experimentally demonstrated that ultrafast optical electric field waveforms with a 2.7 ps resolution and a 40 ps time range can be measured.

    We started this study with the aim of realizing high-speed and high-precision fiber optic sensing by using optical frequency comb that is composed of multiple modes with an equal frequency spacing. The proposed method can perform measurement in short time, because the Brillouin gain spectrum is measured without scanning the frequency of the light source. In addition to simultaneous measurement of Brillouin gain spectrum, the optical sensing based on multimode stimulated Brillouin scattering was demonstrated to be able to perform measurement with a sensitivity three orders higher than the conventional methods. We have also successfully demonstrated multi-point precision fiber optic measurement using fiber Bragg gratings, which is a spin-off of this study.

    The technology for the inspection of the surface profilometry of the product in the manufacturing field was studied. A two-dimensional single-shot miscroscopy, which can measure the distance in the millimeter region with micrometer resolution in the depth direction, was constructed as non-contact measurement using an optical interferometer.Single-shot two-dimensional tomographic images obtained by high-order pseudo-optical comb interference fringes were observed by a CCD with a high volume sampling rate, using an optical comb that can be easily generated as a light source. On the other hand, the fundamental technology of pseudo optical comb interference was developed by developing an ultra-high-speed optical frequency scanning repetition (1 MHz). The repetition rate is faster than the imaging time of CCD and a high-speed discrete wavelength tunable laser, which performs frequency scanning discretely (200 GHz interval) as the light source.

    We have developed optical frequency comb (OFC) synthesizer/analyzer, which basically controls the comb lights on a frequency axis.
    To apply the previous OFC analyzer to single-shot measurement, it is necessary to use a digitizer whose integration time is required to be the time range for the previous OFC analyzer. It is, however, difficult to prepare an ultrafast digitizer covering several ten GHz frequency band corresponding to the 10 picosecond time region. Thus, we have proposed following two new concepts. For the first problem, 5 ps measurement time region was extended to 40 ps by measuring the amplitude and phase spectra with a sampling mode space of 25 GHz intervals between 200 GHz comb mode interval. For the second problem about the difficulty to prepare the fast-capturing digitizer, the single shot measurement was realized with a 1 GHz digitizer by cutting-out the optical dual-heterodyne spectrum in 40 picoseconds time window from continuously repeated waveforms.

    The purpose of this study is to develop a frequency-variable comb generation technology, which enables frequency shift of all modes of broadband comb with wide mode interval at once. In addition, we explore a novel spectroscopy with broad bandwidth and high resolution introducing the frequency-variable laser comb to a spectrograph.
    We confirmed that optical short pulse with 4-ps pulse width and 12.5-GHz repetition rate generated by pulse shaping was frequency-shifted with MHz precision by using a single sideband modulator. After the compression and amplification of the pulse, it was incident on a highly-nonlinear fiber, and we successfully generated a broadband and frequency-variable laser comb ranging from 1100 to 1700 nm. The frequency-variable laser comb was input into the diffraction grating spectrometer and the spectra of low pressure gas and Fabry-Perot filter were obtained with a resolution of 1 MHz.

    In this study, we used an optical frequency comb with wide mode spacing for high dynamic range optical measurement. An optical frequency comb has optical modes at a certain frequency spacing and, generally, the spacing is relatively narrow in the order of 100 MHz. Each lines of such the optical frequency comb has low intensities because the average power is distributed to the large number of the lines. In this study, we used an optical frequency comb whose line-spacing is wider than 10 GHz (multi-gigahertz comb) to obtain high intense comb lines. The high intensity can lead to wide-dynamic-range measurement. To realize the measurement technique, we realized a broadband optical frequency comb with wide mode-spacing and frequency tunability. Finally, we employed the comb as a lightsource for optical measurement.

    We have developed a technique called multi-wavelength electric field heterodyne detection on Fourier space that can measure the asymmetrical ultrafast waveforms with high sensitivity. The relative phase between the adjacent peaks of the optical comb are detected by using the reference optical comb. A prototype and operation of the Fourier space light source system was carried out along the following items.
    1. The 200GHz optical frequency comb of 32 waves was generated with the seed light source of 25GHz optical frequency comb (256 waves).
    2. The pulse train of the optical comb, ie, the electric field spectrum of spectral region was measured in a time of the waveform changing by the digitizer. And it succeeded in reproducing by measuring the waveform within a repetition time by inverse Fourier transformation of the measured light field spectrum.

Ultrafast waveforms were generated by manipulating the amplitude and phase of a gigahertz optical frequency comb (OFC) using a customized colorless optical synthesizer. The synthesized waveform was analyzed on the frequency axis using a dual-heterodyne mixing. The proposed system has been applied to generate femtosecond pulses and to synthesize composite amplitude-shift and phase-shift keying signals.

    We have developed an apertureless SNOM (a-SNOM), and have studied the polarization properties of the a-SNOM. As a result, we have succeeded to obtain a spatial resolution of approximately 10 nm. In addition, we have also succeeded to resolve a SNOM signal and a background signal. FDTD simulation explained our experimental results well, and consequently, we understood electric fields underneath apertureless probes. Furthermore, we developed a system for time-resolved SNOM measurement.

    In order to realize a natural three-dimensional display which is free from visual fatigue, a large number of images have to be displayed simultaneously. This study proposed a new display system which is a hybrid system combining the lenticular display system and the multi-projection display system. The prototype display that generates 256 images was developed. The accommodation responses of humans to the prototype display were measured and we confirmed that the depth range where the visual fatigue does not occur was enlarged.

    The new high-density directional (HDD) display using the time-multiplexing technique is proposed to reduce the complexity of the multi-projection system used for the HDD display. The HDD display is a natural three-dimensional display which has been developed to solve the visual fatigue problem caused by the accommodation-vergence conflict. The proposed HDD display consists of multiple time-multiplexing display modules. Each module consists of an LED array, a DMD, lenses, and an aperture array. A number of directional images are displayed by the DMD at a high frame rate and the LED's emit light one after another in synchronization with the DMD. The apertures are arranged two-dimensionally, and their horizontal positions are different. The LED's are arranged in a same way. All directional images displayed by the DMD pass through different apertures. Multiple modules are arranged two-dimensionally with the different horizontal positions and all images are combined by a common lens. A vertical diffuser is used as a display screen to cancel the difference of the vertical display directions. All directional images are superimposed on the vertical diffuser, and are given the different horizontal display directions. Each module generates 15 directional images at a frame rate of 60 Hz. Four modules are combined to display 60 directional images in the different horizontal directions with the angle pitch of 0.31°.

    In our previous report, the optical frequency comb generator consisting of two phase modulators in tandem we used generated the narrow bandwidth of the comb spectrum, only 2 nm, and resulted in the limited resolution up to 300μm. And some noises of many side-lobes appeared around the interferometric peaks due to a rectangular frequency comb spectrum. Furthermore, it took a long time for the data acquisition because the point-to-point scanning was used in a fiber-optic interferometer.
    To improve the performance of our previous system, we introduced new functions of a broad band frequency comb and a line-type image sensor to realize a frequency comb-based interferometric microscope. One of the improvements in the proposed system is that a broadband frequency comb spectrum of over 10 nm was obtained by combining a waveguide type-frequency comb generator^<6-8)> consisting of the phase modulator installed in the Fabry-Perot cavity and a subsequent wavelength equalizer^<9)>. The depth resolution is finally improved up to 35 μm, and the side-lobes in the interferometric signals also disappeared. Another important improvement is to realize a high-speed observation of three-dimensional images by the use of a line type-image sensor for capturing a line image in a horizontal direction at a time.
    The measurement resolution narrowed finally to 35 μm by introducing the waveguide-type frequency comb generator and the wavelength equalizer. Furthermore, introducing the line image sensor can obtain the simultaneous measurement of the whole horizontal cross sectional image of the interferometric signal. We successfully demonstrated the 3 dimensional surface profilometry of a Japanese 10-yen coin and observation of a cross sectional tomography image of transparent thin films by varying the comb frequency interval without mechanical shift. The dynamic range in the depth direction was about 1.1 mm and the measurement resolution was 35μm. The standard deviation of seven times thickness measurements was 5μm.

    A range of techniques, including coherence scanning microscopy, three-dimensional sensing by coherence radar, and scanning white-light interferometry, have been developed for simultaneous measurement of the three-dimensional step height of discontinuous objects and tomographic imaging. These techniques, however, require mechanical scanning with a piezoelectric transducer or a precision translator. Spectral interferometry, on the other hand, potentially offers a powerful means for high-speed absolute threedimensional shape measurement of objects without moving mechanical parts. The practical applicability of such methods, however, remains limited due to the high cost of tunable lasers with sufficiently wide range (e.g., external cavity laser diodes and dye lasers) and the slow speed of data acquisition because of the large number of calculations in the Fourier transform. As an alternative interferometry-based approach, synthesis of the coherence functions has been reported to be suitable for distance measurements. This method involves pseudo-frequency comb generation by frequency modulation of a laser diode. Yet this method is not suitable for surface profilometry because the frequency-comb interval is limited to the order of megahertz.
    In this Letter, a novel frequency comb-based interferometry technique for profilometry and tomography is proposed. The optical frequency comb employed by this method can be adjusted simply, allowing interferometry to be performed at frequency intervals of up to gigahertz order. The method is therefore suitable for measurement of absolute distances of several micrometers to several meters without the need for mechanical movement.
    Step-height measurement with 9 μm accuracy was successfully performed by sweeping the comb interval frequency. Thickness measurement of a glass plate was also demonstrated. This profilometry method is expected to be useful for both surface profilometry and tomography.
