title: Compact optical data processor employing holographic reflective lenses.
abstract: A compact optical data processor is described that employs holographic reflective lenses. The processor is inexpensive and requires one-half of the length of the optical bench as that required for using glass lenses. The fabrication of the holographic lenses is described, and the results of optical processing reported. The results show that an inexpensive data processor employing holographic lenses is a feasible project. The processor may find use for onboard optical processing on spacecrafts and satellites. The most distinguishing characteristic of such a processor is its extreme light weight. The angular alignment tolerances for holographic lenses are very low. The processor must, therefore, be made rugged, designed, and mounted to withstand vibrations, shocks, and other environmental problems associated with spacecrafts and satellites.
