Highly efficient multi-dimensional data storage and extraction are two primary ends for the design and fabrication of emerging optical materials. Although metasurfaces show great potential in information storage due to their modulation for different degrees of freedom of light, a compact and efficient detector for relevant multi-dimensional data retrieval is still a challenge, especially in complex environments. Here, we demonstrate a multi-dimensional image storage and retrieval process by using a dual-color metasurface and a double-layer integrated perovskite single-pixel detector (DIP-SPD). Benefitting from the photoelectric response characteristics of the FAPbBrI and FAPbI films and their stacked structure, our filter-free DIP-SPD can accurately reconstruct different colorful images stored in a metasurface within a single-round measurement, even in complex environments with scattering media or strong background noise. Our work not only provides a compact, filter-free, and noise-robust detector for colorful image extraction in a metasurface, but also paves the way for color imaging application of perovskite-like bandgap tunable materials.
高效的多维数据存储和提取是新型光学材料设计与制造的两个主要目标。尽管超表面因其对光的不同自由度的调制而在信息存储方面显示出巨大潜力，但用于相关多维数据检索的紧凑且高效的探测器仍然是一个挑战，尤其是在复杂环境中。在此，我们展示了一种使用双色超表面和双层集成钙钛矿单像素探测器（DIP-SPD）的多维图像存储和检索过程。受益于FAPbBrI和FAPbI薄膜的光电响应特性及其堆叠结构，我们的无滤波器DIP-SPD即使在存在散射介质或强背景噪声的复杂环境中，也能在单次测量中准确重建存储在超表面中的不同彩色图像。我们的工作不仅为超表面中的彩色图像提取提供了一种紧凑、无滤波器且抗噪声的探测器，还为类钙钛矿带隙可调材料的彩色成像应用铺平了道路。
