Abstract
Acousto-optic (AO) interaction for a case when an acoustic signal contains three frequency components is theoretically and experimentally investigated. An existence of combinative frequencies at the multifrequency AO interaction is proved. A spatial distribution of transmitted and diffracted light intensities is demonstrated in approximation of three-step scattering process. The functioning of an AO spectrum analyzer is illustrated by an example of the three-frequency AO interaction. A new method for the expansion of the analyzer dynamic range is suggested. The efficiency of the method is experimentally confirmed.
