Abstract

Achieving parallel acquisition of multidimensional optical information for precise environmental sensing constitutes a persistent challenge in imaging system design. Conventional implementations typically necessitate complex optical assemblies, temporal multiplexing strategies, and specialized active illumination sources, imposing fundamental limitations on system miniaturization and practicality. Drawing inspiration from human visual perception, particularly disparity images and optical structures, a metasurface capable of 4D imaging is demonstrated through single‐shot acquisition. Leveraging polarization multiplexing principles and the non‐diffracting, self‐accelerating properties of Airy beams, the metasurface produces spin‐decoupled point spread functions (PSFs) exhibiting horizontal displacement correlated with object depth. This configuration enables the generation of disparity‐equivalent images in the left‐ and right‐handed circular polarization channels. By combining these with the proposed image restoration and depth retrieval algorithms, 4D imaging encompassing 3D imaging and polarization analysis is achieved. This compact multidimensional imaging platform demonstrates significant potential to advance machine vision and autonomous driving applications while offering foundational insights for further high‐performance imaging system development.

单-超表面-启用双目视觉用于4D成像
实现多维光学信息的并行获取以实现精确的环境感知是成像系统设计中的一个长期挑战。传统的实现通常需要复杂的光学组件、时间复用策略和专门的主动照明光源,这对系统的小型化和实用性造成了根本性的限制。从人类视觉感知,特别是视差图像和光学结构中汲取灵感,通过单镜头采集展示了能够进行4D成像的超表面。利用偏振复用原理和艾里光束的非衍射、自加速特性,超表面产生自旋解耦的点扩展函数(psf),显示与物体深度相关的水平位移。这种结构可以在左旋和右旋圆偏振通道中产生视差等效图像。通过将这些与所提出的图像恢复和深度检索算法相结合,实现了包含3D成像和偏振分析的四维成像。这种紧凑的多维成像平台在推进机器视觉和自动驾驶应用方面具有巨大潜力,同时为进一步高性能成像系统的开发提供了基础见解。
