摘　　要：对实时彩色三维动态显示的追求激发了学术界和产业界巨大的研究热情。随着“元宇宙”概念的提出,对高性能三维显示设备与技术的需求越发迫切。全息术是一种理想的三维显示方案,但传统光场调控器件却存在视场角狭窄、信息容量小等问题,阻碍了全息技术的进一步发展。而超表面作为一种新型光场调控器件,有望利用其像素尺寸小和光场调控能力强的特点在全息技术领域实现新的突破。本文主要从超表面全息器件的设计流程、调制方式、动态实现、制造技术四个方面给出了超表面全息十余年的概貌,并提出该领域未来发展的方向。The pursuit of real-time,full-color,three-dimension(3D),and dynamic display has inspired a rich body of industrial and academic research.With the introduction of"Metaverse",there is an increasing demand for high-performance 3D display devices and technologies.Holographic technology is an ideal approach for future naked-eye 3D display.However,traditional dynamic holographic devices have brought many shortcomings such as small field of view(FOV)and limited information capacity,which hinder the practical applications.As a new class of light field modulator,metasurface is expected to achieve remarkable breakthroughs in the field of holographic display with the advantages of their small pixel size and the emerging ability to manipulate light.This paper gives an overview of the development of meta-holography from four aspects:the design strategy,the modulation principle,the methods for realizing dynamic display and the micro-nano fabrication technologies for optical metasurface.We finally include a brief discussion of the future direction in this field.
