Abstract:
The overall objective of this project was to develop an ultrafast target recognition system using holographic techniques, as well as spin-off technologies with other applications. We report here a set of significant accomplishments towards this goal. These include 1 demonstrations of shared hardware operation of a super-parallel holographic correlator and RAM, 2 demonstrations of an ultra-fast holographic stokesmeter for polarization imaging 3 demonstrations of off-axis transmission and reflection holographic lenses for use in the super-parallel architecture 4 demonstrations of a translation-invariant correlation of images stored via holographic angle-multiplexing in a thick photopolymer material 5 development of a large-area, thick, optical quality holographic recording disc capable of storing up to 2 terabyte of data 6 demonstration of real-time, pico-second speed, translation-invariant correlation using a novel photorefractive material, and 7 demonstration of automatic target recognition of targets in a view from arbitrary altitudes and orientations during the flight of a remote-controlled aerial vehicle.
