摘要
从快速反射镜机械结构设计、３８０Ｈｚ高帧频成象探测器及数字控制系统三个方面系统地介绍了基于ＡＳＴ３８６计算机的快速反射镜成象跟踪系统。对提高反射镜机械结构谐振频率和高帧频图象实时处理速度及位置测量精度等问题给出了一些解决方法，并提出在数字控制系统中引入插值算法可虚拟地提高系统采样频率，增加系统带宽。最后给出了实验结果。
An image tracking system with a fine-steering mirror(FSM) based on the AST386 computer is presented. The mechanical design of the mirror, the high frame rate(380 Hz) image detector and the digital control system are discussed respectively. A number of methods are introduced to raise the structural resonance frequency of the mirror, the real-time processing rate for high frame rate image and the measuring precision of positioning. The system's sampling frequency can be increased fictively and the bandwidth can be improved throuhg the use of the interpolating-data in the digital control system. The experimental results are given in the end of the paper.
