摘要：
The influence of the acousto-optic effect on the methodical error of measurement of particle vibration velocity in a liquid is studied. The dependence of this error on the parameters of a measuring installation, length of acoustic wave and the distance between a particle and the plane of laser beams entering into a medium is analyzed. The refraction and diffraction effects and their influence on the methodical errors are taken into account on the basis of a gaussian beam model.
