sinusoidal phase grating meaning in English

正弦型相位光栅

Difference iterative method was used to estimate numerically director configurations in the nlc - bl037 cell in this paper . the refractive indices and phase retard of nlc in electric field was presented on the basis of the calculation of liquid crystal director distributions . then we analysed the diffraction phenomenon when the linearly polarized light was controlled by diffraction grating which was based on rectangular grating and sinusoidal phase grating models and we got it ’ s math model 。 finally we designed the nlc phase grating and we did the experiment to validate the theoretic calculation
文中利用差分迭代法计算了向列相液晶bl037盒中指向矢分布的计算,根据指向矢的分布情况得到了向列相液晶的双折射率分布和非常光通过液晶盒产生的相位延迟随电压变化;并在矩形光栅和正弦相位光栅的基础上,分析了入射偏振光通过液晶电控光栅所产生的衍射情况。
