| 摘 要： | 对电控平行液晶光栅的理论进行了分析,并配以结构原理图。通过对平行排列及90°扭曲排列液晶指向矢的计算,得出液晶盒中相应的折射率、相位差与电压之间的关系图,两者经比较证明平行排列更具适用性,并在实验中观测到了平行排列液晶光栅衍射特性与电压的关系。

| Abstract: | Firstly analyze the theory of the electro-controlled planar alignment liquid crystal grating and present its configuration. The refractive indices and the phase delay of the liquid crystal cell in electric field was presented on the basis of calculation of the planar alignment nematic and the twisted nematic liquid crystal director distributions, through the comparison we found the planar alignment nematic liquid crystal was more applicability . Finally in the experiment, we found out the relation between the diffraction properties of the planar alignment liquid crystal grating and the voltage. |
