Full‐Stokes Spectro‐Polarimetric Camera with Full Spatial Resolution

Abstract In recent years, intelligent optical sensing has seen rapid advancements driven by innovations in optoelectronics and AI‐based algorithms. Specifically, spectro‐polarimetric imaging (SPI) provides comprehensive insights by capturing both spectral and polarization information. In this paper, a spectro‐polarimetric camera is presented that combines full‐Stokes polarimetric imaging with multi‐spectral imaging, achieving full spatial resolution across the visible wavelength range. Utilizing a CMOS‐compatible micro‐filter array and a deep unfolding network (GAP‐net), the camera achieves a spatial resolution of 2016 × 2016 pixels, and successfully resolves 14.30 lines per millimeter, as verified by the USAF 1951 test chart. The camera achieves video‐rate snapshot spectral imaging for polarization‐insensitive scenarios and delivers exceptional spectral reconstruction fidelity for both static and dynamic scenes, with a remarkable fidelity of 99.53% for the standard color checker. For polarization‐sensitive scenes, the full‐Stokes parameters ( S 0 , S 1 , S 2 , S 3 ) are successfully restored, while maintaining the spectral precision. The proposed spectro‐polarimetric camera holds significant importance for high‐dimensional intelligent optical sensing and demonstrates considerable potential in remote sensing, autonomous driving, and surveillance.
