摘要

为了解决传统模式控制型液晶透镜折射率分布偏离理想抛物面的问题，提出了高阻层的方块电阻阶梯分布的模式控制液晶透镜的设计方案。采用模式控制型液晶透镜的电阻-电容等效电路模型，对该设计方案的液晶透镜折射率分布进行仿真研究。将方块电阻等距分为不同阶梯数量，计算了液晶透镜折射率分布与理想折射率分布的偏差，得到不同焦距情况下的最小分段数量。研究了方块电阻阶梯分布固定条件下，改变驱动电压和频率调节液晶透镜焦距时，液晶透镜折射率分布与理想分布的偏差，得到了液晶透镜焦距在280 mm至无穷远范围变化的方块电阻分布方式。

Abstract

In order to solve the problem that the refractive index distribution of the traditional modal-control liquid crystal lens deviates from the ideal parabola

a design scheme of a modal-control liquid crystal lens with a sheet resistance step distribution of a high-resistance layer is proposed. The resistance-capacitance equivalent circuit model of the modal-control liquid crystal lens is used to simulate the refractive index distribution of the liquid crystal lens of this design scheme. The sheet resistance is divided into equally different steps. The deviation between the refractive index distribution of the liquid crystal lens and the ideal refractive index distribution was calculated

and the minimum number of segments was obtained at different focal lengths. The deviation of the refractive index distribution of the liquid crystal lens from the ideal distribution when the driving voltage and frequency were used to adjust the focal length of the liquid crystal lens under a fixed condition of the sheet resistance step distribution was studied. The sheet resistance distribution of the liquid crystal lens with a focal length ranging from 280 mm to infinity was obtained.
