Abstract
Snapshot imaging polarimeters comprise Sagnac interferometers that include diffraction gratings situated to produce shear between counter-propagating optical fluxes produced by a polarizing beam splitter. The counter-propagating, sheared optical fluxes are focused onto a focal plane array to produce fringe patterns. The fringe patterns correspond to a scene polarization distribution modulated onto a spatial carrier frequency associated with a diffraction order. Multi-blazed gratings can be used so that modulations at a plurality of spatial frequencies are produced, with each spatial frequency corresponding to a spectral component of an input optical flux. Modulated fringe patterns can be demodulated to obtain scene Stokes parameter distributions.
