Abstract
A spectroscopic device according to the present disclosure includes: a light source unit configured to output signal light generated from a sample; a Fourier spectroscopic unit configured to receive the signal light, generate a pair of light beams with any time delay, and output first output light obtained by causing the pair of light beams to interfere with each other; a wavelength dispersion spectroscopic unit configured to detect second output light obtained by dispersing the received first output light according to a wavelength; and a control device configured to extract a component of the signal light in the second output light based on a detection result of the second output light.
