摘要

梯度折射率液晶透镜是一种可通过调控电场来改变其空间有效折射率分布来实现变焦的光学透镜。由于它具有焦距自由可调、结构紧凑、稳定性良好等优点，在光学透镜领域受到了广泛的关注。本文介绍了电控梯度折射率液晶透镜的基本工作原理，描述了4种电极类型的梯度折射率液晶透镜：边缘电场驱动的液晶透镜、离散多电极型液晶透镜、高阻层电极型液晶透镜、完整电极或无电极层液晶透镜。通过评价具有代表性的例子全面地展示液晶透镜的发展现状，读者可简单、清晰，直观地了解和掌握电控折射率液晶透镜的发展历程与未来方向，为进一步研究电控梯度折射率液晶透镜提供清晰的基础认知与参考方向。

Abstract

Electronically controlled gradient refractive index liquid crystal lens (EC-GRIN-LCL)is an optical lens that can change the distribution of its spatial refractive index to zoom in out by controlling the electric field. Due to the properties of variable focal length

compact structure and excellent stability

it has been attracting intensive attention in the field of optical lenses. This review introduces the basic working principle of EC-GRIN-LCL and describes four types of liquid crystal lenses driving strategies: (1) by edge electric field

(2) by discrete multi-electrode

(3) by electrode with high resistance layer

and (4) by complete electrode layer or no electrode layer. By introducing

concluding and commenting on the representative instances of the four types of EC-GRIN-LCL

this review aims to provide the readers with a clear basic knowledge

a comprehensive development history and tendency

and a reference for further research of EC-GRIN-LCL.
