Characterization of electromagnetic wave polarization states is critical in various applications materials, biomedical, and imaging. The emergence metasurfaces opens up the possibility implementing highly integrated full-Stokes imagers. Despite rapid development, prevailing schemes on metasurface-based imagers require interleaved or cascaded designs, inevitably resulting performance deterioration, bulky size, complicating imaging procedure due to misalignment. To overcome these challenges, a non-interleaved shared-aperture metalens enabled by prior-knowledge-driven inverse design methodology proposed. can be directly deployed into imagers, performing high-accuracy diffraction-limited without other ancillary components, breaking intrinsic constraints efficiency resolution design. demonstrate this, W-band passive system, as an alternative solution, perform polarimetric imaging, which reduces reliance high cost complexity ortho-mode transducer broadband correlator traditional radiometers. Furthermore, with assistance 3D reconstruction method, feasibility multi-polarization information for contactless surface slope measurements explored. This work may open new paradigms imager designing broaden metasurface

Abstract Metasurface holograms offer various advantages, including wide viewing angle, small volume, and high resolution. However, full-color animation of high-resolution images has been a challenging issue. In this study, dielectric metasurface holographic movie with resolution 2322 × was achieved by spatiotemporally multiplexing 30 frames blue, green, red color channels at the wavelengths 445 nm, 532 633 nm maximum reconstruction speed 55.9 per second. The average transmittance diffraction efficiency 92.0 % 72.7 %, respectively, in visible range, were adopting polarization-independent silicon nitride waveguide meta-atoms, resulting reproducibility. superposition three adjusting resolutions positions target for each wavelength while maintaining meta-atom pitch constant. improvement brought about optimization etching conditions to form high-aspect vertical nanopillar structures.
