High-speed Fourier-transform infrared spectroscopy with phase-controlled delay line
Kazuki Hashimoto, Venkata Ramaiah Badarla, Takuro Ideguchi
Fourier-transform infrared spectroscopy (FTIR) is the golden standard of mid-infrared (MIR) molecular spectroscopic analysis through optically-encoded vibrational signatures. Miche…
Compressive dual-comb spectroscopy
Akira Kawai, Takahiro Kageyama, Ryoichi Horisaki +1
Broadband, high resolution and rapid measurement of dual-comb spectroscopy (DCS) generates a large amount of data stream. We numerically demonstrate significant data compression of…
A multimodal laser-scanning nonlinear optical microscope with a rapid broadband Fourier-transform coherent Raman modality
Faris Sinjab, Kazuki Hashimoto, Venktata Ramaiah Badarla +2
Nonlinear optical microscopy allows rapid high-resolution microscopy with image contrast generated from intrinsic properties of the sample. Established modalities such as multiphot…
Adaptive dynamic range shift (ADRIFT) quantitative phase imaging
Keiichiro Toda, Miu Tamamitsu, Takuro Ideguchi
Quantitative phase imaging (QPI) is often used for label-free single cell analysis with its high-contrast images of optical phase delay (OPD) map. Contrary to other imaging methods…
Enhanced spectral resolution for broadband coherent anti-Stokes Raman spectroscopy
Faris Sinjab, Kazuki Hashimoto, Xuanqiang Zhao +2
The spectral resolution of broadband Fourier-transform coherent anti-Stokes Raman spectroscopy is limited by the maximum optical path length difference that can be scanned within a…
