Abstract

An optical detection system uses high-resolution holographic filters for target detection within a very-large field of view image acquired with a reflector. The holographic filter acts as an optical computer, mixing phase and amplitude information of known targets with light from the scene, automatically enhancing portions of the image that match threat objects or other object of interest. A lens forming a Fourier transform of the entire scene is used, and within that transform, the holographic information of a target or multiple targets is added. By acting as an inverse optical transfer function, the hologram gathers the target information to single point, and removes non-target background. Amplification is done by using a laser-illuminated hologram to create a phase-amplitude filter in a photorefractive material at the transform plane. By mixing the hologram and the scene at the transform plane, the matching is enhanced regardless of target location in the scene.
