Combination of the dual comb spectroscopy with the single-pixel imaging is effectively applied for a scan-less hyperspectral imaging of an object having spectral-dependent absorption.
We propose a hyperspectral imaging method based on the combination of dual optical comb spectroscopy with single pixel imaging. We describe the concept of the method and demonstrate a proof-of-principle experiment.
We proposed spectroscopic ellipsometry employing dual-optical-comb spectroscopy. We demonstrated the ellipsometric evaluation of a high-order quarter waveplate and a SiO2 thin film standard with the spectral resolution of 48 MHz.
We compared images reconstructed by three methods: ghost imaging (GI), Hadamard transform imaging (HTI), and scan-based imaging. Although GI and HTI use a bucket (or single channel) detector, GI has attracted more attention than HTI in recent years. Nevertheless, a direct comparison between them has not yet been conducted to the best of our knowledge. In the present work, we evaluate contrast ratios...
