利用三维数值计算方法分析了具有可调谐锥形透镜特性的液晶透镜的液晶指向矢重取向和光学相位延迟。所提出的LC透镜设计采用圆形电极、环形电极和圆形孔图案化电极，所述圆形孔图案化电极在平坦的液晶盒中采用高电阻层。计算了三维倾斜角和方位角分布。随后，可以估计透镜区域中的圆锥相位延迟。光学相位分布的实验结果与数值计算结果吻合较好。
A three-dimensional numerical calculation for analyzing reorientation in liquid crystal (LC) directors and optical phase retardation in an LC lens, which exhibits a tunable conical lens property, is developed. The proposed LC lens design employs a circular electrode, ring electrodes, and a circularly hole-patterned electrode employing a highly-resistive layer in a flat nematic cell. The three-dimensional tilt and azimuthal angle distributions are calculated. Subsequently, the conical phase retardation in the lens region can be estimated. The experimental results obtained for the optical phase profile agree well with the numerically calculated results.
