摘要
实现基于四象限红外探测器的位置检测信号处理系统。从四象限位置探测的原理入手,介绍了探测器信号提取与前级放大电路、同步相干谐波检测电路,以及模数转换、时序控制、数据采集电路。实验结果良好,系统可行。
The purpose is to introduce the signal processing system of position detection based on four-quadrant infrared detector. It shows how the four-quadrant infrared detector works, and includes signal acquire circuits, amplifying and filter circuits, phase-lock circuits, A/D circuits, and data acquisition circuits. The result of experiment is excellent and the system is effective.
