Liquid crystal lens with concentric electrodes and inter-electrode resistors

Abstract

In this review, we provide an overview of recent efforts in designing high-quality tunable liquid crystal (LC) lenses with concentric electrodes. The design concepts are introduced, and details about fabrication and evaluation methods are given. Computational and experimental approaches are used to gain understanding of the fundamental limiting factors affecting the performance of LC lenses. In addition, directions for improvement of image quality, speed, optical power, and off-axis performance are proposed.
