摘要：液晶透镜是自由3D显示的新器件，其原理是利用基于向列相液晶指向矢随外加电场作用发生变化的
光电特性。本文提出一种简易准确的透镜参数设计和优化方案。以单圆孔结构的液晶透镜为例，利用光学
软件ZEM A X和焦距缩放法对圆孔结构的液晶透镜的参数加以设计并优化。分析液晶透镜的像差，评价

质量。结果表明，优化后的液晶透镜的像差明显减小，3.5°视场下，弥散斑均方根半径R M S值由248. 118 #〇微生物发酵床
减小到62. 1:2 #〇，为原来的25. 1j；光学调制传递函数M T F值明显改善。最后实验测试验证了液晶透镜阵
列的衍射光斑亮度及清晰度均显著提高。

Abstract：Liquid-crystal lenses are newdevices for free 3D display，i t s photoelectric properties are
controlled by electric field. The accurate design and optimization metliod of lens parameters were
presented in this paper. Based on the optical software Z E M A X and the focal length zoom method，压脉带
the parameters of L C D s were designed and optimized. T h e n，the aberration of liquid crystal l image quality were evaluated. i t i s proved that the optimized liquid crystal lens aberration evidently. The d ispersion spot root mean square radius (R M S)value decreases from 248. 118 #m to
62. 192 #m witii 3.5° view and the optical modulation transfer function M T F i s improved. The ex
perimental results show that the brightnes and clarity of the difractive lens array are significantly
improved.
