光学编码器是长度和角度测量最常用的传感器
两种传统光学编码器:绝对式和增量式光学编码器的光学图案、位置编码原理和信号处理电路各具特色
随着科学技术的发展
一种新型光学编码器方案:准绝对式编码器
继承了二者的优点
根据其串行位置编码原理
借助计算机辅助设计
获得了全周100个位置的编码方案
设计了相应的准绝对式编码器;通过与两种传统编码器特点的比较
突出了准绝对式光学编码器的显著特点
指明了其未来良好的应用和发展前景.
Optical encoder is an important sensor used for length and angle measu rement
and two conventional optical encodes
incremental and absolute enco d ers
have outstanding advantages in optical pattern
principle of position code and signal processing circuit. With development of science and technology
a new optical encoder
virtual absolute encoder has inherited the advantages of these two conventional optical encoders. According to the principle of s erial position code
a scheme of 100 positions around a circle has been obtained with CAD. Using this position code a virtual absolute encoder has been designed.
