Abstract : This patent discloses a photo-reconnaissance/surveillance system in which the landscape to be scanned is photographed on color film. The film is then developed in a highspeed processor and scanned by photosensors. Illuminations for the sensors is provided by a plurality of point sources of light. Colored filters e.g., a green filter and a blue filter, are alternately interposed between the light sources and the film. A logic circuit compares the transmission through the film for both light conditions and, thus, can detect the presence of a target, if the color signature of the target is known a priori. (Author)
