An Opticoacoustic Correlation Spectral Analyzer,

Abstract

The Patent concerns the field of radioengineering and is designed for the analysis of radio signal spectra. An opticoacoustic correlation spectral analyzer is known, containing a mixer, a band filter, a radio pulse generator and an indicator. The aim of the invention is to increase the product of the analysis band with times the analysis time and to speed up the analysis process. This is achieved by the fact that an opticoacoustic correlator with two ultrasonic light modulators is introduced into the analyzer, in which ultrasonic waves propagate in opposite directions. One of the modulators is connected to the output of the band filter, the other to the output of the radio pulse generator. (Translations, USSR, Russian Language).
