Dual-comb spectroscopy is a new Fourier transform spectroscopy using two optical combs with slightly different repetition frequencies as light sources. In recent years, we have applied this method to solid sample spectroscopy and developed an all fiber type dual comb spectrometer that is compact and easy to adjust alignment. In this study, we aimed at realizing high speed and high accuracy temperature measurement by incorporating an fiber Bragg grating (FBG) in all-fiber-type dual-comb spectrometer.
