Abstract
Systems and methods prevent friendly fire using infrared object recognition. An IR projector projects a beam of IR radiation at a first wavelength onto the object and an IR detector, having a field of view of the object, detects IR fluorescence from the object, where a wavelength of the fluorescence is a function of the first wavelength. The system includes a memory for storing software having machine readable instructions that, when executed by a processor, perform the steps of: (a) controlling the IR projector to generate IR at the first wavelength; (b) controlling the IR detector to capture the object fluorescence; and (c) identifying the object as friendly or non-friendly based upon the object fluorescence. The system further includes an inhibitor for preventing firing of a gun or missile when the object is identified as friendly.
