Optical spectral device based on an acoustooptic tunable filter with a frequency-hopping change of the control signal

Abstract

An acoustooptic modulator is considered as an element of a system for processing signals in the radio and optical range with a lattice-like structure. The importance of spectral measurements of the optical range in science and technology is noted. A method is proposed for measuring the spectra of optical signals with an idealized spectral device based on an acoustooptic tunable filter. A method for measuring the spectrum of an optical signal with a spectral device based on an acoustooptic tunable filter with a frequency-hopping change in the frequency of the control signal is presented. The mathematical model of the optical system is described as a bilinear spectral transformation of acoustooptical interaction. An exhaustive characteristic of the optical spectrum analyzer is calculated – its complex instrumental function.
