摘要
超透镜作为一种二维超表面结构最近十多年来得到了广泛的关注.与传统光学透镜相比,超透镜具有超薄和超轻的结构特性以及高度灵活的设计和调控能力,因此,其在推动光学系统向小型化发展中扮演着不可或缺的角色.在显微成像技术中,超透镜又提供了多维度的探索视角,展示了其巨大的发展空间.本文全面回顾了超透镜在显微成像技术的最新进展.首先,详细解释了超透镜的波前调控原理,并总结了超透镜主流的设计方法;其次,介绍了超透镜的加工技术;最后,深入探讨了超透镜在光片荧光显微镜、双光子荧光显微镜和内窥镜等显微成像技术中的应用和研究进展.
Abstract
Metalens,a two-dimensional metasurface structure,has attracted widespread attention in the last decade.Compared with conventional optical lenses,metalenses are featured with ultra-thinness and ultra-lightness,as well as multifunctional design and modulation capabilities.Thus,they play an indispensable role in promoting the development of optical systems to miniaturization.In microscopic imaging technology,metalenses provide a multidimensional perspective,which demonstrates their great potential in innovation.In this paper,the recent progress of superlensing in microimaging technology is comprehensively reviewed.First,the wavefront modulation principle of metalens is elaborately explained and the design method of metalens is summarized.Second,the main fabrication techniques of metalens are introduced.Finally,the applications and research progress of metalens in microscopic imaging technologies are insightfully reviewed,such as light-sheet fluorescence microscopy,two-photon fluorescence microscopy,and endoscopy.
