为解决目前摆镜检测系统采样率低，难以满足高频摆镜测量需求的问题，根据等效采样原理，设计了基于高速激光闪频技术的多时序高精度非接触式摆镜检测系统。该系统首先利用激光脉冲控制电路实现多时序的闪频激光照明，在CCD靶面上获得光斑位置图像；然后，根据激光光斑成像位置计算摆镜的摆角，并依照相邻光斑位置之间的时间间隔得到角速度。实验结果表明：检测系统的角度分辨力为0.005°，动态采样时间间隔可以达到百微秒量级，角速度测量误差小于±7%。该系统提高了摆镜测量的采样率，满足了高频摆镜测试的要求。

In order to solve the problem of low sampling rate and to meet the requirements of high frequency swing mirror measurement, based on the principle of equivalent sampling, a multi time series high accuracy non-contact swing mirror detection system is designed. First, with the laser pulse control circuit, multi time sequence flashing laser lighting is achieved and the spot position is obtained on the CCD target plane. Then, according to the image of the laser spot position, calculate the mirror swing angle and angular velocity by the time interval between adjacent spot positions. The experimental results show that the angle resolution of the detection system is 0.005°. The time resolution can reach the microsecond order, and the angular velocity measurement error is less than ±7%. The system improves the sampling frequency of swing mirror measuring and meets the requirements of high frequency swing mirror test.
