The paper proposes a novel method to enhance the robustness of optical information transmission using disordered metasurfaces. By manipulating the spatial coherence structure and coherence length of light beams, the metasurfaces can achieve ultra-robust optical information transmission and self-reconstruction even when most of the light is obstructed. The method involves loading a random wavefront with a specific correlation function onto the metasurface, which then accurately manipulates the incident beams to have predefined spatial coherence structures and coherence lengths. The experimental results demonstrate that the proposed metasurface can generate partially coherent beams with prescribed spatial coherence structures, such as Hermite-Gaussian and Laguerre-Gaussian correlated Schell-model beams, and achieve robust optical information transmission and self-reconstruction. This approach provides a generic principle for generalized coherence manipulation and has potential applications in advanced optical technologies, including meta-holography and imaging in disordered media.The paper proposes a novel method to enhance the robustness of optical information transmission using disordered metasurfaces.
