  • Patent number: 4411489
    Abstract: A system for synthesizing strip-multiplexed holograms, with or without coherent light, from a plurality of two-dimensional images. The two-dimensional images may be formed by a motion picture film of a rotating subject such that each image is a view of the subject from a different angle. The images are then non-diffusely and anamorphically projected by a lens system which compresses the image in a first direction and expands the image in a second direction orthogonal to the first direction. The projected image or object beam is then superimposed on the reference beam by a lens-beamsplitter which transforms the substantially planar object beam into a substantially cylindrical wavefront and projects it and the reference beam onto a holographic recording medium. As each two-dimensional image is sequentially projected, the holographic recording medium is shifted so that a plurality of laterally displaced strips are recorded.
