单模光纤反射式结构光纤电流传感器温度敏感性分析
|
摘要
本文针对采用单模光纤作为传感元件的反射式光纤电流传感器的温度敏感性进行分析。从理论上分析了采用法拉第旋光镜的反射式结构可以有效去除固有双折射的影响,该作用对单模光纤也适用。温度敏感性实验也证明了反射式光纤电流传感器确实具备稳定性。
The temperature sensitivity of reflective optical fiber current sensor using single-mode optical fiber as sensing element is discussed in this paper. And it analyzes that the reflective structure using Faraday rotating mirror can effectively remove the influence of intrinsic birefringence of sensor system in theory,which is also applicable to single-mode fiber. The temperature sensitivity experiment also proves that the reflective fiber optic current sensor is indeed stable.
