由于一般的液晶显示器件都使用了偏振片，对其参数的测试类似于偏光元件的测试，系统的偏光响应会影响某些参数的准确评价。通过分析液晶器件参数测试系统ＬＣＴ５０１６， 我们发现光谱仪的偏振依赖性敏感度和部分偏振的光源严重影响了某些测试结果。探讨了一系列的消除偏光响应的方法，包括测试过程和光学系统的设计。我们设计的补偿器能够在整个可见光谱范围内有效地消除偏光成分。这些方法可用于消除一般光学测试系统中的偏光响应。
Since most liquid crystal display devices use a polarizer, the test of the parameters is similar to that of a polarizer. The system’s polarized response may affect the accurate evaluation of certain parameters. By analyzing LCT5016, a parametric test system for liquid crystal devices, we found that the spectrometer’s polarization-dependent sensitivity and partially polarized light sources have severely affected some of the test results. A series of methods to eliminate polarization responses were explored, including the testing process and the design of the optical system. The compensator we designed effectively eliminates polarized components over the entire visible spectrum. These methods can be used to eliminate the polarizing response in typical optical test systems.
