Abstract
A holographic structure, system and method project a grey-scale image in a narrow IR spectral band that is related to a broadband thermal signature of an object. The projected grey-scale image, when integrated over the broadband, forms either a decoy that approximates the thermal signature of the object or a mask that obscures the thermal signature of the object. The projected image is a tuned phase recording of a desired far field projection. In different embodiments, the projected image is a 'positive' or a 'negative' image of the object's thermal signature, a difference image between the thermal signatures of a false object and the object or a camouflage image of random features having approximately the same spatial frequency as the object's thermal signature. The goal being to confuse or fool, even for a short period of time, the warfighting or surveillance system or human observer that uses a broadband IR sensor to acquire and view thermal images of the scene.
