声光相互作用产生频移和拍频的理论已经较为完善，但没有具体变化规律的描述。从实验出发，利用高频探测器结合共焦扫描干涉仪和频谱分析仪，用实验方法通过研究Raman-Nath衍射点的拍频现象直观地将声光相互作用产生拍频的现象展示出来，对拍频的产生机理进行了相关分析，并总结了拍频形成的规律，对其产生的条件等因素做了探索。

The theories of frequency shift and beat frequency generated by acousto-optic interaction are more perfect, but the detailed changing rules are not described. Based on experiments and with a high frequency detector, a confocal scanning interferometer and a spectrum analyzer, through researching the beat frequency phenomena of Raman-Nath diffraction point, the beat frequency phenomena generated by acousto-optic interaction is directly shown. The generation principle of beat frequency is analyzed. The generation rule of beat frequency is summarized.
