Abstract

The acousto-optic interaction at a water surface perturbed by random waves and by an underwater sound source is studied. The interferometric method is applied to measure the features of the power spectra of the scattered light field. Detection of sound-induced perturbation of the rough surface is performed. The corresponding theory of the scattered light spectra modulation is presented and its results are compared with the data of the experiment.
