Abstract: An imaging system for identifying camouflaged or concealed objects includes an image sensor for receiving at least a portion of reflected light from an interrogation region having foliage including at least an ultraviolet (UV) including band. The image sensor includes a 2-D photodetector array that has a plurality of photodetector pixels that provides sensitivity to the UV band. The 2-D photodetector array generates at least a first detection signal from at least the UV band. A green light filter can be added to exclude green light in the background from being detected. A processor for data processing is coupled to an output of the photodetector array that forms processed image data from at least the first detection signal. The processed image data can be used to generate a visual image that reveals camouflaged or concealed objects, or be used for automatic detection of camouflaged or concealed objects.

Abstract: A single aperture polarimetric color imaging system includes a color filter array including a plurality of RGB filter elements in a path of received radiation that includes color band and near IR light. A linear polarizer array includes a plurality of polarization filter elements that provide a plurality of different polarization orientations that are optically aligned with the RGB filter elements. A single common pixel array includes a plurality of photodetector pixels for transducing the color band or near IR light into electrical signals after processing by the color filter array and linear polarizer array. A band select switching device switches between selectively transmitting the near IR band and color band or color band including light. A signal processor is coupled to receive and process the electrical signals from the common pixel array and generates polarimetric image data from the near IR band light and color image data from the color band or color band including light.
