摘　　要：超表面全息术的出现极大地促进了全息成像技术的发展,同时也拓展了电磁超表面的应用范围。为进一步梳理超表面全息成像的发展脉络,以技术发展的时间轴为主线,系统地回顾了超表面技术的发展历程,以及受益于超表面技术的全息成像模式的进步。随着技术的进步,超表面全息术逐渐从可见光频段向微波频段发展,从静态重现向动态全息演变,因此,着重介绍了超表面全息术的未来方向——可重构超表面及其动态全息技术,并且从超表面单元高性能创新技术、超表面阵列全息模式以及超表面全息系统研究3个方面对可重构超表面全息术的发展做了展望。The emergence of meta-surface holography is greatly promoted to the development of holographic imaging technology and the application range of electromagnetic meta-surfaces.In order to further clarify the development trajectory of meta-surface holography,this paper systematically reviews the development process of meta-surface technology and the progress of holographic imaging modes benefited from meta-surface technology.With the advancement of technology,the meta-surface holography gradually evolves as the microwave frequency band from the visible light frequency band,and as dynamic holography from static reproduction.Therefore,the discussion of this paper centers on the introduction of meta-surface holography-reconfigurable meta-surfaces and their dynamic holographic technology to the future direction.For the above-mentioned reasons,this paper prospectively discusses the development of reconfigurable meta-surface holography,high-performance innovation technology of meta-surface element,holographic modes of meta-surface,and meta-surface holographic system research.
