摘要
:提出一种等间距排列的三探头反射式光纤位移传感器 ,该传感器通过双路接收的方法来实现光强补偿。从理论上对该种传感器的补偿机理作了详细的分析 ,得出了位移特性调制函数的表达式 ,给出了仿真曲线。结果表明 ,这种光纤传感器可以有效地消除因光源光强波动。
A reflective fiber-optic displacement sensor of three probes with equal transverse space is introduced. The sensor can perform automatic compensation by two receiving optical fibers. The compensation mechanism of this sensor is analyzed in detail, and at the same time the displacement modulating function and corresponding simulating curves are presented. Results show that this sensor can effectively eliminate the influence to output characteristics caused by power fluctuation, difference of surface reflectivity and transmission loss.
