The results show that the linear birefringence will modulate the scale factor of the system with a Sa function, it can also affect the extent of the influence of the incident polarizing angle, taking －sin2;(δ/2) as the influence factor, at the same time. When the incident polarizing angle has some special values such as 0,45, or 90 degree, the effect to the system will be zero.

结果表明，线性双折射会以Sa函数的形式调制理想光学玻璃电流传感器输出信号的尺度因子，同时以－sin2(δ／2)为影响因子决定入射起偏角对系统影响的大小；当入射起偏角取某些特殊值时其对系统的影响为零。
