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 (S0, S1, S2, S3) 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.
