Polarization and its detection have attracted tremendous attention due to the rich information it provides and the practical applications it enables. Here, we propose a high-performance reflective pixelated metasurface with full-Stokes detection in the visible wavelength, which integrates both linear polarization (LP) and circular polarization (CP) filters on one platform. The system achieves a high extinction ratio for CP incidence in a non-Hermitian system, generated from the exceptional point (EP) effect. With integrated LP filters, full-Stokes detection can be obtained with accuracy and efficiency in real time. The EP-based innovation also promises other practical applications, such as polarization imaging technologies and optical computing.
