  • Patent number: 6028621
    Abstract: A three-dimensional image is reproduced by unit 3. For that purpose, the interference pattern on carrier 8 is illuminated by source 7 of noncoherent reproduction radiation. The process is that of illuminating the first interference structure 5, which is optically coupled with the interference pattern, or the second interference structure 9, the principle of spatial filtration of which corresponds to the principle of spatial filtration of the first interference structure 5 and the scale of which corresponds to the scale of the interference structure illuminated. The beams are extracted the intensities, spatial positions and directions of which correspond to the intensities, spatial positions and directions of the beams that were registered in recording the interference pattern, i.e., the beams are extracted which correspond to the independent spatial coordinates .alpha. and .beta.. The set of these beams corresponds to a three-dimensional image of object 4, which is indistinguishable from the real image.
