本文叙述了一种包含有声光调制器的激光调相系统。利用它测量了压电变形反射镜的频响特性。给出了压电变形反射镜没有调制时的拍频结果。同时,还给出了该反射镜进行相位调制的自振频率。
This article describes a laser phase modulation system that includes an acousto-optic modulator. Use it to measure the frequency response characteristics of the piezoelectric deformation mirror. The beat frequency results of the piezoelectric deformation mirror without modulation are given. At the same time, the natural frequency of phase modulation of the reflector is also given.
