摘要

本文描述了一种利用相位编码和编码补偿系统提高增量式旋转编码器分辨率和精度的方法。将该系统应用于标距为1/36000的光学增量编码器，获得了1/920000的旋转分辨率和优于+或1/300000的旋转精度(+或0.0012度)。该系统还可用于速度波动的精确测量。

A method of improving the resolution and accuracy of rotary encoders using code compensation technique

A method for improving the resolution and accuracy of incremental type rotary encoders using a phase encoding and code compensation system is described. Applying this system to an optical incremental encoder whose scale pitch is 1/36000, a rotation resolution of 1/920000 and a better than +or-1/300000 rotation (+or-0.0012 degrees ) precision are obtained. The system can also be used for a precise measurement of speed fluctuation.<>
