Analysis of Overlapping Spectra by Metods of Difraction Spectrometry

In connection with the advent of a new high-frequency digital techniques generation that allows harmonic signal creation with a sufficiently sharp phase change and the required period it has become possible to createan acousto-optic spectrometer for direct measurement of the optical radiation spectrum derivatives. The paper presents the results of the study of the differential spectrometer created at the NTC Unique Instrumentation RAS on the basis of an acousto-optic cell with a sharp phase modulation of the operate voltage.
