| 摘 要： | 提出在圆光栅作为分度基准的高精度测量仪器中，利用A/D转换器和单片机，采用软件编程的方法，对光栅读数头输出信号进行新的构建，形成一分段线性函数。实现了莫尔条纹八细分，从而使角度测量达到较高的精度。与传统的细分法相比，硬件电路简单，细分误差小，且便于误差修正。

| Abstract: | In the high precision measurement instrument using the radial gr ating as the graduated reference,a linear signal is generated from the signals t hat are the output of the grating reader.By detecting the zero points of the gen erated signal and the original signals,the eight-fold subdivision for MOIR frin g es is carried out.Thus high precision angle measurement is realized.Compared wit h the common subdividing techniques,it has those advantages, such as simple ele ctronic circuit,little subdividing error,and convenient for error correction. |
