我们展示了在可拉伸的聚二甲基硅氧烷衬底上用金纳米棒制作的具有最多三个像面的可重构的纯相位计算机生成的亚表面全息图。拉伸基片会放大全息图像并改变像平面的位置。在拉伸时，这些设备可以在多个不同的图像之间切换显示的全息图像。这项工作为可伸展的亚表面全息图作为可动态重新配置的光通信和显示的平面器件开辟了可能性。这也证实了可伸缩衬底上的亚表面可以作为各种可重构光学器件的平台。
We-demonstrate reconfigurable phase-only computer generated metasurface holograms with up to three image planes operating in the visible regime fabricated with gold nanorods on a stretchable, polydimethylsiloxane substrate. Stretching the substrate enlarges the hologram image and changes the location of the image plane. Upon stretching, these devices can switch the displayed holographic image between multiple distinct images. This work Opens up the possibilities for stretchable metasurface holograms as flat devices for dynamically reconfigurable optical communication and display. It also confirms that metasurfaces on stretchable substrates can serve as platform for a variety of reconfigurable optical devices.
