Abstract: The system and method for imaging having filter containing polarized elements, multispectral elements or both being oscillated in circular or linear motion so each individual pixel will view a scene thru the individual filters. The motion of the filter is synchronized with a frame rate of an imager. In one example this is accomplished by micro actuators. Each pixel sampling feeds a processor detection algorithm that determines if a multispectral/polarization signature is present in the scene.

Abstract: A ground imaging system for use on a guided aerobody includes one or more lenses designed to receive EM radiation from a ground level, a filter substrate having a plurality of filters, a sensor array designed to receive the EM radiation from the filter substrate, and a processing device coupled to the sensor array. The filter substrate is located at a focal plane of the one or more lenses such that the filter substrate receives the EM radiation from the one or more lenses. The plurality of filters includes at least polarization filters and multispectral filters. The processing device is designed to analyze multispectral and polarization signatures of the electromagnetic radiation from identified objects at the ground level and determine that one or more of the objects is not a desired target based at least on the hyperspectral and polarization signatures of the one or more objects.
