Transient properties of a liquid crystal lens with multiple divided circularly hole-patterned electrodes

Optical phase retardation distributions and transient properties of a liquid crystal (LC) lens with multiple divided circularly hole-patterned electrodes and external electrode are experimentally measured and numerically analyzed for an LC molecular orientation in a consideration of time domain by using a three-dimensional (3D) finite-difference method. The dynamical behaviors of the reorientation in LC directors and of the phase retardation in the LC lens with positive and negative lens properties are compared.
