介绍一种新型光栅测控电路，该电路由少量集成电路、单片微机及AC-DC电源组成，使用元件少，线路简单，可用于使用直光栅及光电编码器的精密位移测量及控制。
A new type of grating measurement and control circuit is introduced, which consists of a small number of integrated circuits, single-chip microcomputers and AC-DC power supplies. It has fewer components and simple circuits and can be used for precision displacement measurement and control using linear and optical encoders.
