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ZEMAX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，评价成像质量。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RMS值由248.118 m减小到62.192 m，为原来的25.1%；光学调制传递函数MTF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 new devices for free 3D display

its photoelectric properties are controlled by electric field. The accurate design and optimization method of lens parameters were presented in this paper. Based on the optical software ZEMAX and the focal length zoom method

the parameters of LCDs were designed and optimized. Then

the aberration of liquid crystal lens and image quality were evaluated. it is proved that the optimized liquid crystal lens aberration decreases evidently. The dispersion spot root mean square radius (RMS) value decreases from 248.118 m to 62.192 m with 3.5 view and the optical modulation transfer function MTF is improved. The experimental results show that the brightness and clarity of the diffractive lens array are significantly improved.
