Title: SHORT WAVE INFRARED POLARIMETER
Abstract:
A short wave infrared polarimeter comprising a pixelated polarizer array and an Indium-Gallium-Arsenide ("InGaAs") focal plane array, such that interlaced images of different polarization states are collected in a single image and are used to compute intensity and polarized images of the scene. The short wave infrared polarimeter optionally includes a micro-lens array and/or an aperture layer.
