It would result in the fluctuation of the sensitivity of the system because of the existing of the dispersions of the reflection-induced retardance,Verdet constant and the linear birefringence inside the sensing head.

而在传感头中主要是由单层保偏反射膜的反射相移、光学玻璃的Verdet常数以及光学玻璃内的线性双折射这三个因素的色散特性，使得光学电流互感器的灵敏度随光源波长的变化而改变。

The effects of the central wavelength shift of the source and the variations of the parameters of the sensing head (Verdet constant and linear birefringence) due to ambient temperature fluctuation upon the scale factor of a bulk-glass optical current transformer are theoretically analyzed and digitally simulated.

用理论分析和计算机仿真的方法研究了环境温度变化导致的光源中心波长移动和传感头材料Verdet常量与应力双折射变化对光学电流互感器输出性能的影响。
