Abstract: A series of experimental studies to the light beam deflection angle based on acousto-optic effect are presented. Based on the tradition acousto-optic effect＇ s basic principle, we establish the light beam deflection angle theoretical model and carry on the related computation. Our result through the massive Bragg diffraction experiment shows that where is a difference for the size of surveys light beam deflection angle and the theoretical value.

Key words: acousto-optic effect, Bragg diffraction, light beam deflection
