    We evaluated the optical properties of various types of silica glass with different OH-group concentrations by using terahertz (THz) time-domain spectroscopy. The results show that the absorption coefficient in the THz frequency region varied with the OH-group concentration and that the variation depended only on the OH-group concentration, irrespective of the glass-manufacturing process. On the other hand, the refractive index did not depend on the OH-group concentration. Thus, the THz optical properties of silica glass can be predicted based on the OH-group concentration in the glass, and vice versa.

    We demonstrate and report the feasibility of utilizing terahertz (THz) surface emission from semiconductors as a mapping tool for magnetic field distribution. Using a standard THz time-domain spectroscopy setup, the THz emission of indium antimonide (InSb) was systematically measured at several different points of an external magnetic field. The initial results suggest promising directions in developing a practical THz emission-based magnetic field mapping technique for non-destructive electromagnetic imaging applications.
  • Gigahertz time-domain spectroscopy and imaging for non-destructive materials research and evaluation.
    Bulgarevich Dmitry S;Shiwa Mitsuharu;Furuya Takashi;Tani Masahiko
    Scientific reports 6 2016
    :By using optical sampling with repetition frequency modulation of pump/probe laser pulses on photoconductive emitter/detector antennas, the high-speed time/frequency domain gigahertz imaging is reported due to the absence of opto-mechanical delay line in this optical scheme. The clear contrast for a 3-cm wide metal plate, which was placed behind a 5-cm thick concrete block, was observed with a 1窶堰~窶褀1窶盈m image pixilation. On average, it took only ~0.75窶鋭 per pixel/waveform acquisition/assignment with a 675 ps time-domain window. This could become a valuable non-destructive evaluation technique in gigahertz spectral range with all benefits of time-domain spectroscopy.
