英文摘要	基于像散原理的光学检测系统,是通过对光路系统聚焦信号的离焦量fES的检测实现微位移的测量。四象限光电探测器作为检测系统的光电转换传感器,需要设计光电探测器电路,实现对fES信号的检测,并由微单片机系统采集处理,通过串口通信传给PC机进行数据存储和被测对象二维图像分析和重建。通过将所设计的电路集成在光学测头装置上进行实验测量,光电转换信号稳定,相对误差小于5%。; The optical detection system based on the principle of astigmatic to measure the micro displacement is through detecting the defocused quantity FES of fouce signal in optical system.Four quadrant photoelectric detector as the photoelectric sensor of the detection system,have to design the circuit of photoelectric detector,to achieve FES detection,the FES signal is collected and processed by micro SCM system,storage the data to PC and analysis and reconstruction 2d image of the tested object through serial communication.Integrated the circuit to the optical probe decive and to measure the micro displacement,photoelectric signal stability,the relative error less than 5%.
