Abstract

We present an experimental multichannel polarization imaging system based on a polarization diffraction grating (PDG). The PDG simultaneously creates six diffraction orders, each having a different polarization state. For this proof-of-concept experiment, we encoded the PDG onto a parallel-aligned liquid-crystal spatial light modulator (LCSLM), using a double-pass optical architecture. We use a birefringent object where the top is covered with a retardation film and the bottom is isotropic. We show experimental results, where we simultaneously produce six images of this birefringent object, each with a different polarization state. The proposed technique can produce a single-shot imaging polarimeter.
