当测量要求采取不受漂移和强度误差影响的数字形式时 ,采用线性或角度数字编码器。本文设计了一种数字光纤传感器 ,通过光的反射实现增量式数码器的数码读取与识别。我们提出了用 2个码道的编码器响应在左 -右 (或顺时针 -逆时针 ) 2个方向上的变化。分析表明该位移传感器具有较强的抗零漂和抗强度误差的能力
Linear or angular digital encoders are used when the measurement requires digital form that is immune to drift and strength errors. In this paper, a digital optical fiber sensor is designed to realize the digital reading and recognition of incremental digital device by the reflection of light. We propose a 2-code encoder response in two directions, left-right (or clockwise-counterclockwise). Analysis shows that the displacement sensor has strong anti-drift and anti-strength error ability
