Abstract
The processes of acousto-optical interaction at infra-low frequencies are studied using seismic vibrators as sources of low-frequency acoustic oscillations propagating in the atmosphere and laser measuring lines as optical receivers of vibrations. The proposed types of the source and receiver for the purpose of studying acousto-optical interaction determine the novelty and originality of the proposed approach. The results of experiments on evaluating the characteristics of acousto-optical interaction at infra-low frequencies in problems of laser environmental monitoring are presented.
