Abstract

We propose a novel laser-scanning optical microscopy employing optical-frequency-comb (OFC) lasers. Laser-scanning OFC microscopy enables unique spectroscopic imaging by analyzing an interferogram of OFC. The interferogram has a lot of information involved in light such as amplitude, phase, polarization, frequency, and time of flight information. Thus, multimodal imaging is expected to become possible with only a single measurement by using these various light information. We provide a proof-of-principle demonstration of laser-scanning OFC microscopy in a variety of applications, such as spectroscopic amplitude, phase, polarization, and time of flight imaging. Our approach would be a useful and powerful tool for microscopic observation.
