Title:
SPECTROSCOPIC DEVICE, SPECTROSCOPIC METHOD, RAMAN SCATTERING ANALYSIS DEVICE, LUMINESCENCE SPECTROSCOPIC ANALYSIS DEVICE, AND HARMONIC OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/166569
Kind Code:
A1
Abstract:
A spectroscopic device according to the present disclosure comprises: a light source unit which outputs signal light generated from a sample; a Fourier spectroscopic unit which receives input of the signal light to generate a pair of light beams with a suitable time delay and which outputs first output light obtained by causing the pair of light beams to interfere with each other; a wavelength dispersive spectroscopic unit which detects second output light obtained by spectrally dispersing the inputted first output light according to the wavelength; and a control device which extracts a component of the signal light included in the second output light on the basis of a result of detecting the second output light.
