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…
Scan-less hyperspectral dual-comb single-pixel-imaging in both amplitude and phase
Kyuki Shibuya, Takeo Minamikawa, Yasuhiro Mizutani +4
We have developed a hyperspectral imaging scheme that involves a combination of dual-comb spectroscopy and Hadamard-transform-based single-pixel imaging. The scheme enables us to o…
