| 摘 要： | 在利用法拉第(Faraday)效应的混合型光纤传感器中,通常用全反射改变光的传递方向,以增加有效光程,并使结构紧凑。反射将改变光的偏振状态,从而影响传感的灵敏度。本文用琼斯(Jones)矩阵方法推导了有反射时传感头的传光特性,分析了反射对检测灵敏度的影响,获得了与实验一致的结果。

| Abstract: | In hybrid current fiber sensors operating on the Faraday effect, reflection ig often used for changing the propagating direction of light to increase the effective optical path and to make the structure of the sensos compact. But the reflection changes the polarization of light, and consequently have an effect on the sensor's sensitivity. In this paper, Jones matrix method is used to derive the propagating characteristics of the sensor. The effect of reflection on sensor's sansitivity has been analysed and the results obtained agree with experimental data. |
