Abstract
A spectroscopic device and the like that are capable of fast spectral dispersion are provided. The spectroscopic device includes: a modulation unit for converting wavefront shapes of light according to wavelengths; and a demodulation unit for changing a phase of light of a selected wavelength within the light whose wavefront shapes have been converted, in such a way that the light changes into a predetermined state.
