AI 中文摘要
波前整形是缓解复杂介质散射的关键技术,可实现先进成像与光通信。然而现有方法本质上是局域的,需要空间光调制器或可变形镜等主动校正元件直接位于散射光的光路上,这限制了其在紧凑型成像系统中的集成。本文通过实验演示了利用空间纠缠光子对实现非局域波前整形:对从未与散射介质相互作用的光子施加相位校正,以补偿其纠缠伙伴所经历的畸变并恢复两者初始空间关联。该方法将波前校正与散射介质物理解耦,为在紧凑型及其他难以进入的系统中实现透过复杂介质成像铺平了道路。
英文摘要
Wavefront shaping is a key technique for mitigating scattering in complex media, enabling advanced imaging and optical communication. Yet existing approaches are inherently local, requiring active correction elements - such as spatial light modulators or deformable mirrors - to lie directly in the optical path of the scattered light, which limits their integration into compact imaging systems. Here, we experimentally demonstrate nonlocal wavefront shaping using spatially entangled photon pairs. By applying a phase correction to a photon that never interacts with the scattering medium, we compensate for the distortions experienced by its entangled partner and restore their initial spatial correlations. Our approach physically decouples the wavefront correction from the scattering medium, paving the way for imaging through complex media in compact and otherwise inaccessible systems.
