Analyzis of Functioning of Acousto-Optic Spectrum Analyzer with Spatial Integration in Case of Acoustic Beam Divergence

Abstract

The functioning of homodyne acousto-optic spectrum analyzer with acoustic wave divergence taken into consideration is observed. It is shown that divergence leads to sufficient irregularity of acoustical pressure and farther to the frequency resolution degradation.
