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。

Because the liquid crystal material is birefringent, light passing through one polarizing filter is rotated by the liquid crystal helix as it passes through the liquid crystal layer, allowing it to pass through the second polarized filter.

因为液晶材料是双折射，光线穿过一个两极化的过滤器是旋转液晶螺旋，因为它通过液晶层，允许它通过第二偏振过滤器。
