By leveraging form birefringence, metasurfaces can serve as multifunctional freespace polarization optics. Metasurface gratings are novel, to the best of our knowledge, polarimetric components that integrate multiple polarization analyzers into a single optical element enabling the realization of compact imaging polarimeters. The promise of metasurfaces as a new polarization building block is contingent on the calibration of metagrating-based optical systems. A prototype metasurface full Stokes imaging polarimeter is compared to a benchtop reference instrument using an established linear Stokes test for 670, 532, and 460 nm gratings. We propose a complementary full Stokes accuracy test and demonstrate it using the 532 nm grating. This work presents methods and practical considerations involved in producing accurate polarization data from a metasurface-based Stokes imaging polarimeter and informs their use in polarimetric systems more generally. & COPY; 2023 Optica Publishing Group English Optical Society of America Evaluation and characterization of imaging polarimetry through metasurface polarization gratings Article 10.1364/AO.480487 1 Applied Optics, v.62, no.7, pp.1704 - 1722 Applied Optics 62 7 1704 1722 Y scie scopus 001042424800001 2-s2.0-85149146409 Optics Optics Article DIELECTRIC METASURFACES AEROSOL PROPERTIES LAND SURFACES RETRIEVAL OPTIMIZATION CALIBRATION MISSION CAPABILITIES
