摘要
为获得无偏振效应分束器（NPBS）光学参量对正交共轭反射镜电流传感器性能的影响的规律并为该种传感器设计提供理论依据，用实验方法获取了NPBS反射相移和分光比的温度特性，并用理论方法研究了其对正交共轭反射镜电流传感器性能的影响．结果表明，尽管当温度在5℃～40℃范围内变化时，NPBS的分光比和反射相移均发生了变化，但只有分光比的温度特性影响系统输出的灵敏度的稳定性；通过对尺度因子进行温度补偿可保证系统输出的温度稳定性．
Temperature effects on reflection-induced retardance and the splitting ratio of non-polarizing beam splitters （NPBS） were experimentally investigated to determine their influence on the optical parameters of an NPBS and orthoconjugate reflector current sensors （OCRCS）. The effect of temperature on OCRCSs were theoretically analyzed. The results show that, although the splitting ratio and reflection-induced retardance change when the temperature varies in the range from 5 ℃ to 40 ℃, only the splitting ratio influences the stability of the output sensitivity of the system. This provides a theoretical foundation for OCRCS design, whereby temperature compensation to the splitting ratio coefficient can ensure the stability of the system.
