摘　　要：偏振转换器能够通过对入射光偏振态的动态调控间接实现几何相位型多功能光学器件光学响应特性的动态可调。基于液晶的偏振转换器具有调控效率高、调控面积大、紧凑化程度高等诸多优势,是目前应用较为广泛的偏振转换器。本文围绕偏振转换效率、工作波段、视场角3个核心参量,系统介绍了液晶偏振转换器最新的研究进展,分别给出了典型液晶偏振转换器和大视角宽波段液晶偏振转换器的详细结构和性能表现,同时介绍了液晶偏振转换器工作波段和视角的拓展方法。该项工作能够为液晶偏振转换器结构设计与应用提供必要的参考,同时为基于几何相位或新型相位调控模式的研究提供一些思路。Polarization converters can indirectly achieve dynamic adjustability of the optical response characteristics of geometric phase multifunctional optical devices by dynamically adjusting the polarization state of the incident light.Polarization converters based on liquid crystal have many advantages such as high control efficiency,large control area,and high compactness,etc.,making them the most widely used polarization converters at present.This article systematically introduces the latest research progress of liquid crystal polarization converters based on the three core parameters of polarization conversion efficiency,operating frequency band,and field of view angle.The detailed structures and performance performances of typical liquid crystal polarization converters and large angle and wide band liquid crystal polarization converters are presented.The expansion methods of operating frequency band and angle of view for liquid crystal polarization converters are also introduced.This work can provide necessary references for the structural design and application of liquid crystal polarization converters,and also provide some ideas for research based on geometric phase or novel phase control modes.
