Polarization Diversity Active Imaging is a new active imaging technique which illuminates a scene or target with a sequence of polarization states and then measures images of the polarization state scattered from a scene. These polarization images are then analyzed to determine the polarization characteristics at each pixel by measuring the Mueller matrix image, then mapping the retardance, diattenuation, and depolarization images over the scene. These data sets are used to estimate the plane of incidence and target orientation pixel by pixel.
