Meta-grating-lens-based monolithic polarization camera.

ABSTRACT: Polarization imaging has the powerful ability to detect unique features invisible to human eyes, which is challenging for conventional intensity imaging systems. Metasurface emerges as a transformative platform for compact polarization imaging systems, but prior strategies suffer from limited imaging field-of-view (FOV) and coarse-grained polarization pixels. Here, we demonstrate a meta-grating-lens (MGL)-based monolithic polarization camera achieving 14° FOV and real-time full-Stokes polarization imaging in the near-infrared region. The optimized MGL exhibits >60% focusing efficiency with <3% zeroth-order noise, enabling simultaneous polarization analysis, beam-splitting, and imaging functionalities in a fine-grained pixel level. This synergistic design enables both efficient light utiliz
