Abstract

The problem of holographic associative memory in the framework of the correlation-optical approach is discussed. Analysis of models of referenceless holograms and nonlinearly registered off-axis holograms, reconstructed in associative method, shows a wide range of useful properties of such holograms. Not only to reconstruct the missing part of the stored data set but also to detect small changes ("errors") in the recorded picture an array of data with error correction for an incomplete version of the array as well as for the implementation of high-performance heteroassociative reconstruction based on the non-interference mechanism of partial signals. It is shown that the visually assessed quality of the reconstructed associative response can approach the image quality achieved in conventional off-axis holography.
