We developed a new laser scanning optical-frequency-comb spectroscopic microscope that can acquire spectroscopic informations of amplitude and phase of light simultaneously. It has spatial resolution in the optical axis direction and is capable of high sensitivity measurement by focusing of the laser beam. We built an optical-frequency-comb microscope that introduces optical systems of laser scanning confocal microscope. It revealed that it is possible to acquire spectral images in simultaneous measurement of amplitude and phase of light.
