摘　　要：光栅测量系统应用广泛,常用于高精度的数字信号检测系统中。本文首先分析了几种常用的光栅信号采集方案,然后针对高频干扰信号,提出了技术改进方案,最后介绍了光栅信号采集的PLD/FPGA实现。实验结果表明,使用PLD实现对光栅信号的采集,在很大程度上提高了系统的整体可靠性。Grating Measurement System is used for precise digital signal detection system. In this paper, we first analyze several common methods of grating signal collection, and then advance an improved technology method, finally, introduce the PLD/FPGA realization of grating signal collection. The experimental results show that the advanced method of grating signal collection realized by PLD can effectively improve the whole reliability of system.
