Abstract
A system to produce interconnections between a planar input array and a planar output array using a holographic planar array made by a single exposure or multiple exposures of a photosensitive medium incorporated therein at each of M.times.N positions in said holographic planar array to store the weighted interconnections to connect each input of the O.times.P input array to any one or any combination of outputs in the R.times.s output array in parallel with the strength of connection for each output being determined by the weighting factors as stored in said holographic planar array unadjusted or as adjusted by one or more modulating devices incorporated therein when the optically aligned system is illuminated from any one or any combination of V.times.W sources each of which produces a beam of electromagnetic radiation singular in time or any combination of such V.times.W sources in parallel with each such source producing a different wavelength or any combination of such V.times.W sources producing the same wavelength of electromagnetic radiation and any one or any combination of the positions of the O.times.P input array are connected to either an electrical signal source or to an optical signal source.
