Abstract
White-light snapshot channeled linear imaging (CLI) polarimeters include polarization gratings (PGs) configured to produce a compensated shear between portions of an input light flux in first and second polarization states. The disclosed CLI polarimeters can measure a 2-dimensional distribution of linear Stokes polarization parameters by incorporating two identical PGs placed in series along an optical axis. In some examples, CLI polarimeters are configured to produce linear (S, S, and S) and complete (S, S, Sand S) channeled Stokes images.
