Abstract
A spectral resolution enhancement device including a preliminary dispersion unit, a two-grating angular dispersion amplification unit, and a detection unit is provided. The preliminary dispersion unit is configured to receive collimated incident light and emits light of different wavelengths in the incident light at different angles. The two-grating angular dispersion amplification unit is configured to diffract the light of different wavelengths and emitted from the preliminary dispersion unit multiple times, such that angular dispersion the light of different wavelengths is enhanced, and emergent angle deviations between the light of different wavelengths are increased. The detection unit is configured to detect light of different wavelengths and emitted from the two-grating angular dispersion amplification unit. Since the emergent angle deviations of light of different wavelengths are increased, resolution of the detection unit for the light of different wavelengths is increased.
