标题： Inverse-Designed Metasurfaces for Wavefront Restoration in Under-Display Camera Systems

摘要： 屏下摄像头（UDC）系统通过将摄像头嵌入显示屏面板下方，实现了智能手机的全屏幕显示，消除了缺口或打孔的需求。然而，显示屏面板的周期性像素结构引入了显著的光学衍射效应，导致成像伪影和视觉质量下降。传统的缓解这些畸变的方法，例如基于深度学习的图像重建，通常计算成本高昂且不适合消费电子产品的实时应用。本文介绍了一种逆向设计的超表面，用于波前恢复，解决了由衍射引起的畸变而不依赖外部软件处理。所提出的超表面有效抑制了由金属像素结构引起的高阶衍射模式，恢复了光学波前，并在多个波长上提高了成像质量。通过消除对基于软件的后期处理的需求，我们的方法为UDC系统中的衍射管理建立了一个可扩展的、实时的光学解决方案。这一进展为许多工业应用实现无需软件的实时图像恢复框架铺平了道路。 显示英文摘要

摘要： Under-display camera (UDC) systems enable full-screen displays in smartphones by embedding the camera beneath the display panel, eliminating the need for notches or punch holes. However, the periodic pixel structures of display panels introduce significant optical diffraction effects, leading to imaging artifacts and degraded visual quality. Conventional approaches to mitigate these distortions, such as deep learning-based image reconstruction, are often computationally expensive and unsuitable for real-time applications in consumer electronics. This work introduces an inverse-designed metasurface for wavefront restoration, addressing diffraction-induced distortions without relying on external software processing. The proposed metasurface effectively suppresses higher-order diffraction modes caused by the metallic pixel structures, restores the optical wavefront, and enhances imaging quality across multiple wavelengths. By eliminating the need for software-based post-processing, our approach establishes a scalable, real-time optical solution for diffraction management in UDC systems. This advancement paves the way to achieve software-free real-time image restoration frameworks for many industrial applications.
