Holographic associative memory that is able to retrieve complete objects from their partial or rotated and changed in position inputs is presented. Angularly or spatially multiplexed Fourier-transform holograms of an object and of its synthetic discriminant function respectively, recorded with angularly multiplexed reference beams onto thermoplastic tape or disk are used as the memory elements.
