摘　　要：透镜阵列是由多个透镜按照一定的方式排布而成的多功能光学元件。与单个透镜相比,其可以采集更多的光场信息,具有高速运动探测、三维光场成像、并行信息处理等功能。近年来研究人员将人工微结构材料——超构表面制备成超构透镜阵列,不仅具有传统微透镜阵列的功能,更具有灵活设计、超轻超薄等优势,在光学器件和系统的微型化、智能化、集成化方面具有重要的应用潜力。本文将首先介绍透镜阵列的工作原理,其次将介绍近年来超构透镜阵列在成像和信息技术领域的成功应用,并最终展望超构透镜阵列技术未来的发展。Lens arrays,composed of multiple lenses arranged in a specific configuration,are versatile optical components.In contrast to individual lenses,lens arrays have the capability to capture a greater amount of spatial light field information,thereby enabling functionalities such as high-speed motion detection,three-dimensional light field imaging,and parallel information processing.Recently,researchers have developed metalens arrays that preserve the capabilities of traditional microlens arrays while offering advantages such as flexible design and ultra-lightweight features.The unique attributes of metalens arrays endow them with notable prospects for application in the miniaturization,intelligence,and integration of optical devices and systems.This article describes the working principles of lens arrays,successful applications of metalens arrays in imaging and information technology,and presents a prospective outlook on the future development of metalens arrays.
