Abstract

Recent attempts aimed at developing holographic neural networks and associative memories have stimulated interest to the problems of coherent correlation processing of optical data. Finding new approaches to the reconstruction of the optical field amplitude and phase from its intensity distribution is also a topical problem. In the present work, correlation filters, based on referenceless holograms (RH), are proposed which are the necessary components of neural networks and associative memories. The RH was first introduced as a generalized correlation filter by Van Heerden. A RH is the scattered field intensity recorded on a recording medium. Image reconstruction from such a hologram is based on its associative properties, which take effect when a field (or its part) which is the same as (or similar to) the original object field, is used as the reconstructing field.
