摘要
主要针对磁悬浮球系统中非接触式位移检测,依据感光器件的光伏效应原理,阐述了非接触式光电传感器的研究与设计,实现了光电信号测量微位移。通过磁悬浮球实验研究表明该传感器的精度(0.01mm)和响应速度(<0.1ms)均达到预期要求,从而给出了一种方便、低成本的位移检测方法。
The authors describe their research and design of photoelectric sensor according to a photoemission principle of the photocell, with which micro-distance measurement is realized in the magnetic levitation ball system. The experiment results show that the precision(O.O1 ram) and quick response( 〈 0. 1 ms) of this kind of sensor can meet the preset requirements. Thus a low - cost and convenient way for measuring displacement without contact is provided.
