校准角编码器(或回转编码器)通常使用人工方法与机械参考标准(如精密分度台或多角镜)进行比较。用这种普通方法校准编码器的所有分度是一项很困难的工作,需要熟练的技巧且消耗大量的时间。本文介绍一种适用于各种数字角编码器并具有高精度和高效率的自动校准系统。校准圆周度盘和角编码器的基本方法可分两种:a.用一个比需要校准的角编码器精度更 Calibration angle encoders (or rotary encoders) are typically compared manually to mechanical reference standards such as precision index tables or polygon mirrors. Using this common method to calibrate all of the encoder’s indexing is a difficult task, requires skillful skill, and consumes a lot of time. This article describes an automatic calibration system for a wide range of digital angle encoders with high accuracy and efficiency. There are two basic ways of calibrating a circular disc and an angle encoder: a. Use a more accurate encoder than the one you need to calibrate
