摘要
本文介绍的激光转角传感器,首次将激光多卜勒原理应用于转角非接触测量。推导出以脉冲数表示转体转角值的公式。对传感器的若干理论问题作了详细分析。给出了用该传感器在滚齿机上测量的数据并对传感器的改进作了进一步探讨。
A laser rotating angle sensor is intruduced in this paper. It is the first time to measure the rotating angle contactlessly based on the principle of laser-doppler a formula for calculating the value of the rotating angle by counting the number of the pulses is presented. Several theoretic prorlems related to this sensor are analysed in detail. The data obtained with this sensing element to measure the rotating angle on hobbing maching are given and the way for improving this transducer is further discussed.
