用光电编码器测量直线位移

Measurement of Line Displacement with Photo electronic Encoder

分析了用光电编码器测量直线位移的原理 ,介绍了用数字电路和单片机两种实现直线位移的测量方法。两种方法都能够解决光电编码器测量直线位移时的符号判别及加减运算问题 。

The principle using photo-electronic encoder to measure line displacement is analyzed in this paper.Two methods are introduced,one uses digital circuit,another uses single-chip computer.Both of them resolve the problem of symbol judge and the caculation of plus and minus when photo-electronic encoder is used in the measurement of line displacement.Two methods can be used in different condition,having a good application value.
