扭曲向列型液晶空间光调制器偏振分光特性的实验测试
Experimental Test for Polarized Splitting Light Characteristic of Twisted Nematic Liquid-Crystal Spatial Light Modulator
摘要: 实验测试了线偏振光入射至扭曲向列型液晶空间光调制器(TN-LCSLM)后，输出光强与TN-LCSLM前后放置的两个偏振片旋转角度间的关系。结合理论分析验证了扭曲角为90˚的TN-LCSLM在零灰度图像驱动下的偏振分光特性与强度合成原理。研究结果为深入认识TN-LCSLM的调制特性提供新的研究思路。
Abstract: When a linearly polarized light is incident to a twisted nematic liquid-crystal spatial light modu-lator (TN-LCSLM), the relationships of output intensity and rotating angles of two polarizers placed in front and behind of it are tested experimentally. Cooperated with theoretical analysis, it confirms the principle of polarized splitting light and composed intensity of TN-LCSLM with twisted angle of 90° under zero gray image unloaded. The studied conclusion can provide new idea for clearly understanding the TN-LCSLM’S modulation characteristic.
