摘要
幅值型光纤传感器光源的不稳定性会引起较大的测量误差。我们发明了一种控制光幅值的负反馈光环路。本文详细地介绍了该环路的工作原理和结构,并叙述了有效的补偿电路。
The unstability of the light source of amplitude fibre optic sensorusually causes the larger errors.Now we have invented a kind of negative feedbacklight loop to control the light amplitude of the sensor.This paper introducesin detail the working principle and structure of this loop,and describes theeffective compensated circuit as well.
