利用双折射效应和偏振调制原理, 设计了一种实用化的反射式光纤温度传感器, 分析了精度、 灵敏度等测量的主要指标与光源、 双折射晶体及传输光纤之间的相互关系, 并进行了相应的实验, 给出了系统参数选择的最佳设计方案。

Based on the birefringence effect, a practical reflective fiber-optic temperature sensor was developed with the polarization-modulated method. The relations among the accuracy, sensitivity and parameters including the source, crystal and optical fiber, are analyzed in terms of theory and experiments. The methods of selecting the optimal system parameters are illustrated.
