Paper Abstract

One of the main directions in the development ot present-day systems Of information processing is the creation of neural net- works. In holography neural networks are amply long known: as early as in 1963 P.I.Van Heerden showed that the coupling by means of 3-D gratings which are recorded in a deep 3-D hologram is purely unambiguous In particular, the grating recorded in the hologram by the radiation of two arbitrary points interacts only with the radiation of its 'own' points and ignores that of all other ones during the reconstruction. But most unfortunately, a deep 3-D hologram is not a convenient element when used in practice. In particular, in this case it is very difficult to choose a suitable light-sensitive material and to control each separate grating among a great number of similar gratings which are superimposed in the hologram volume. The report is devoted to the consideration of so-called pseududeep holograms the properties of which are similar to those of 3-D deep holograms, and which are free of the above-mentioned dxbacks.
