Claim One:
1. A real-time electronic automultiscopic imaging system to present three-dimensional images with lateral parallax, said system comprising: a screen HOE comprising a lateral array of holograms wherein each hologram, when reconstructed, produces one or more line images; a multiplexer HOE comprising a two-dimensional array of holograms, wherein each said hologram when reconstructed produces a spot on said screen HOE, the sum of all spots produced by all said holograms of said multiplexer HOE forming a two-dimensional array of spots on said screen HOE, and wherein each said spot produced by said holograms of said multiplexer HOE is produced by at least two laterally offset holograms or portions of holograms of said multiplexer HOE; and a real-time two-dimensional image projector to project two-dimensional images onto said multiplexer HOE whereby real-time variable combinations of said holograms, or portions of said holograms, of said multiplexer HOE are selectively reconstructed and thereby produce a real-time variable pattern of spots on said screen HOE.
