Recently, with the increase of the demand of distance measurement using the light, various measurement techniques have been studied and developed. In the inside, we newly proposed the low-coherence dual-comb spectroscopy based on the dual-comb spectroscopy this time. This technique enables high-speed and high-precise measurement without using a mode-locked light source. In this paper, we report the principle of this method and the results of distance measurement simulation.
