摘要

时空编码元曲面在文章编号 2302164 中，Yan Shi 及其合作者提出了一种时空编码元曲面，用于实现多重全息图成像。通过时空编码方案，可以精确、快速地控制高阶谐波的幅度和相位。所设计的元面可通过±1阶谐波在一个成像平面上实现两个不同图像的近场全息重建，并同时实现全息成像和光束转向或全息成像和轨道角动量波生成等多功能。

Space-Time Coding Metasurface For Multifunctional Holographic Imaging (Adv. Mater. Technol. 12/2024)

Space-Time Coding Metasurfaces

In article number 2302164, Yan Shi and co-workers present a space–time coding metasurface to achieve multiple hologram imaging. Via the space-time coding scheme, the magnitude and phase of the higher-order harmonics can be accurately and rapidly controlled. The designed metasurface enables near-field holographic reconstruction of two different images on an imaging plane by means of ±1st order harmonics, and simultaneous realization of versatile functions including hologram imaging and beam steering or hologram imaging and orbital angular momentum wave generation.
