[LCT2-3L(Invited)] Low-Driving-Voltage Liquid-Crystal-Lenses with High-Resistive Films
liquid crystal lens, focal length, phase retardation, circularly-hole patterned electrode, ring electrode
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 lens property, is developed. The proposed LC lens design employs a circular electrode, ring electrodes, and a circular hole-patterned electrode employing a highly-resistive layer in a flat nematic cell.
