摘要: 对声光效应中光束偏转角进行了一系列实验研究.基于传统声光效应的基本原理,建立了光束偏转角理论模型并进行了相关计算.在此基础上进行声光效应的布拉格衍射实验.大量实验结果显示,所测量到的光束偏转角和理论值存在一定的差距.

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
