Abstract

To describe the speckle metrology technique of detecting the medium acoustic oscillations, the acousto-optic modulator circuit was assembled. It is based on the process of double laser beam propagation through a medium with regular phase changes induced by the acoustic wave. Spectral analysis of photocurrent, obtained by direct photodetection of the laser radiation, allows us to detect frequency of acoustic oscillations in the medium. According to presented scheme the computer model is developed. The simulation results, obtained for the various parameters of the acoustic wave, are described. The case of excitation of two acoustic waves with different frequencies is partially considered.
