AbstractWe propose development of a 'smart' optical preprocessor that installs as an integral part of the light gathering optics of first- or second-generation forward looking infrared imaging systems (FLIRs). This optical preprocessor is based on an advanced-art imaging acousto-optic tunable filter (aka, A-O filter). These newly-configured A-O filters are programmable to seek out specific spectral features of any potential target, at video rates, with throughputs approaching 100%, and with diffraction-limited clarity. One device can be made to operate from the UV to the mid IR. This versatility far surpasses any other spectral imaging approach. Every object has (or can be given in painting) a unique IR optical signature. In our concept, emblems or 'flags' are painted on friendly targets giving unique IR signatures but still camouflaged in the visible spectrum. These paints are modified formulations of camouflage coatings. Two example approaches are deuterated-modified and IR laser dye-modified polyurethane camouflage paints. Deuterated-modification shifts the IR absorption bands around 3.4 um while IR laser dyes will provide intense absorption lines in the near IR 90.7-1.1 um). Non-friendly targets, of course, can also be directly acquired and identified using the same optical preprocessor hardware. Once their IR spectral signatures are known, camouflaged targets used by foes can be isolated from background clutter. In other missions, objects such as vegetation types (i.e. coca plants) or vapor cloud hazards (e.g., chemical, biological or carcinogenic) can also be identified through their optical signature.
