Paper Abstract

The acousto-optical spectrum analyzer for radio-astronomy with high frequency resolution designed on the base of semiconductor laser is described in the article. The investigation results of main spectrum analyzer characteristics are presented. The operation of hybrid opto- digital processor which includes the acousto-optical spectrum analyzer is described. The spectrum analyzer has bandwidth of 115 MHz and frequency resolution of 200 kHz. Its dimensions are equal to 245 by 150 by 50 mm3. The possible acousto-optical spectrum analyzer applications for radio-astronomy are suggested.
