Dual-optical-comb spectroscopic ellipsometry
Takeo Minamikawa, Yi-Da Hsieh, Kyuki Shibuya +8
Spectroscopic ellipsometry is a means to investigate optical and dielectric material responses. Conventional spectroscopic ellipsometry has trade-offs between spectral accuracy, re…
Scan-less confocal phase microscopy based on dual comb spectroscopy of two-dimensional-image-encoding optical frequency comb
Eiji Hase, Takeo Minamikawa, Shuji Miyamoto +10
Confocal imaging and phase imaging are powerful tools in life science research and industrial inspection. To coherently link the two techniques with different depth resolutions, we…
Real-time absolute frequency measurement of continuous-wave terahertz wave based on dual terahertz combs of photocarriers with different frequency spacings
Takeshi Yasui, Kenta Hayashi, Ryuji Ichikawa +7
Real-time measurement of the absolute frequency of continuous-wave terahertz (CW-THz) waves is required for characterization and frequency calibration of practical CW-THz sources.…
Adaptive sampling dual terahertz comb spectroscopy using free-running dual femtosecond lasers
Takeshi Yasui, Ryuji Ichikawa, Yi-Da Hsieh +9
Dual terahertz (THz) comb spectroscopy is a promising methods for high accuracy, high resolution, and broadband THz spectroscopy because the mode-resolved THz comb spectrum possess…
Super-resolution discrete-Fourier-transform spectroscopy using precisely periodic radiation beyond time window size limitation
Takeshi Yasui, Yuki Iyonaga, Yi-Da Hsieh +5
Fourier transform spectroscopy (FTS) has been widely used in a variety of fields in research, industry, and medicine due to its high signal-to-noise ratio, simultaneous acquisition…
Gapless dual-comb spectroscopy in terahertz region
Takeshi Yasui, Yi-Da Hsieh, Yuki Iyonaga +6
We demonstrated combination of gapless terahertz (THz) comb with dual-comb spectroscopy, namely gapless dual-THz-comb spectroscopy, to achieve the spectral resolution equal to widt…
