摘要
在液晶指向矢计算的基础上,本文得到了向列相液晶在电场下折射率分布和相位延迟。并在矩形光栅和正弦相位光栅的基础上,分析了液晶衍射光栅对入射光一级衍射情况及其衍射效率,得到了它的数学模型。
The refractive indices and phase retard of NLC in electric field was presented on the basis of the calculation of liquid crystal director distributions. Deeper analysis of the theory on the phenomenon of the control to the incident light＇s first diffraction light and its diffraction efficiency by diffraction grating based on rectangular grating and sinusoidal phase grating and we got it＇s math model.
