Abstract

Experimental correlation results using invariant filters in an acousto-optic processor are presented and compared with simulation results. Zero and 15 phase state filters are used. Phase-encoded input as well as intensity input examples are given. A variety of invariance ranges are used, with target-specific discrimination included in the filter construction. The acousto-optic processor is described.
