摘要
分析了目前国内提高光栅式光学分度头精度的研究现状，在此基础上提出了光栅式光学分度头的改进方法．对自行设计的逻辑电路作了具体说明，提出了六倍频的细分电路．使得光栅式光学分度头不但实现了数字化，而且显示精度达到１０”．文中还提出了进一步改进和提高的方向．
This peper analyzes home made grating dividing head for its precision improvement.An improved method for grating optics dividing head was raised. The grating optics dividing head was brought about digital display, and the precision achieves 10'. Finally, the direction for its further improvement was pointed out.
