Broadband polarization-based method for color high-resolution imaging through complex scattering media

In complex media scattering, multiple scattering severely degrades the optical wavefront and results in blurred images, while the spectral distortion caused by the scattering effect leads to severe color distortion. Achieving color high-resolution imaging through scattering media remains a significant challenge. Here, we propose a broadband, polarization-based method for color high-resolution imaging through scattering media. This approach enables high-resolution reconstruction by effectively separating the speckle illumination pattern from the mixed-scattering field information, leveraging polarization common-mode characteristics. Concurrently, it incorporates chromatic balance compensation to correct spectral aliasing in the scattered light field, enabling color high-resolution imaging through complex scattering media. To further optimize color distortion caused by scattering, a compensation strategy combining color constancy and white balance theory is adopted. Experimental results demonstrate that the proposed method significantly enhances both spatial resolution and color fidelity across various scattering conditions and target materials, showcasing strong adaptability and robustness. This approach provides an effective solution for achieving high-resolution color optical imaging in complex scattering environments.
