摘　　要：对光栅尺输出正交方波信号四细分计数速度做了研究,分别采用软件与硬件细分计数法对光栅尺信号进行处理.通过实验对比得出,硬件细分电路速度远高于软件细分电路,最大计数速度为7.2 m/s.因此,硬件计数完全可以满足光栅四细分计数要求.Counting speeds of four segments of quadrature grating output square wave signals are researched in this paper, and software and hardware counting methods are applied to handle grating signals. The comparison of the test results shows that the hardware division circuit can fully meet the requirements of four grating segments because the speed of hardware division circuit is much higher than that of the software division circuit.
