摘要

针对光束在级联式液晶偏振光栅传播过程中的斜入射现象会改变其椭圆率进而降低衍射效率的问题，提出了基于偏振补偿的级联式液晶偏振光栅衍射效率优化方法。运用扩展琼斯矩阵分析斜入射角度对液晶偏振光栅相位延迟的影响，结合斯托克斯参数求解不同斜入射角度下液晶偏振光栅出射光束椭圆率的变化，利用矢量衍射理论完成级联式液晶偏振光栅衍射效率模型的建立。基于液晶分子指向矢分布建立斜入射下液晶电控波片的坐标系，分析斜入射角度对液晶电控波片相位延迟的影响，推导出液晶电控波片相位延迟与椭圆率的关系。通过优化液晶电控波片的工作电压补偿斜入射造成的退偏量，实现对椭圆率的偏振补偿。搭建实验平台验证了理论的准确性与方法的有效性。根据测量结果可知，当光束偏转角度从-5°偏转到5°时，本文所提方法提高了级联式液晶偏振光栅3%~4%的衍射效率。

Abstract

Aiming at the problem that the oblique incidence of beam during the propagation of cascaded liquid crystal polarization gratings will change its ellipticity and reduce the diffraction efficiency， an optimization method of diffraction efficiency of cascaded liquid crystal polarization gratings based on polarization compensation is proposed. The effect of oblique incidence on retardation of liquid crystal polarization grating is analyzed by using extended Jones matrix. Combined with Stokes parameter， the ellipticity of liquid crystal polarization grating outgoing beam at different oblique incidence angles is analyzed. Based on the vector diffraction theory， the diffraction efficiency model of cascaded liquid crystal polarization gratings is established. Based on the liquid crystal molecular direction vector distribution， the coordinate system of liquid crystal variable retarder under oblique incidence is established. The influence of oblique incidence angle on retardation of liquid crystal variable retarder is analyzed， and the relationship between retardation and ellipticity is derived. By optimizing the operating voltage of liquid crystal variable retarder， the depolarization caused by oblique incidence is compensated to realize the polarization compensation of ellipticity. The experimental platform is set up to verify the accuracy of the theory and the effectiveness of the method. According to the measurement results， when the beam deflection angle is from -5° to 5°， the proposed method improves the diffraction efficiency of the cascaded liquid crystal polarization gratings by 3%~4%.
