In this research, we tried to obtain a normalized transmission spectrum by separating the center burst and the free-induced decay (FID) of the interferogram on the time axis, which was obtained through dual comb spectroscopy, and extracting a baseline spectrum. The accuracy of this approach is evaluated by comparing with the baseline correction technique used in high-precision spectroscopy.
