Abstract
Metasurfaces are diffractive optical elements composed of subwavelength structures that, when leveraging birefringence, can serve as multifunctional freespace polarization optics. Metasurface gratings are flat optical elements designed to operate as full Stokes analyzers to enable compact polarimetric imaging. This work presents the calibration of a metagrating-based Stokes imaging system. A prototype metasurface full Stokes imaging polarimeter concept is compared to a benchtop instrument for 670, 532, and 460 nm metagratings. The metagrating Stokes imaging polarimeters are assessed for DOLP accuracy within ±0.5%. The 532 nm instrument is fully evaluated for polarization ellipse and degree of polarization accuracy.
