摘要
本文采用了双路光纤接收方法,给出了一种可实现光强自动补偿的光纤位移传感原理。理论上,分析了该传感器的补偿机理,给出了该传感器特性调制函数的理论表达式,并对理论结果进行了实验验证。
With twin receiving optical fiber method, a fiber--optic displacement sensingprincip which can perform the intensity compensation automatically is intro-duced in this paper.Theoretically, the compensation mechanism of this sensor isanalyzed and the characteristic modulating function given. Finally, the theo-retical results are confirmed by experiments.
