ABSTRACT:
A hologram capable of reconstructing a multicolor three-dimensional image is formed in which a plurality of standing wave interference fringe patterns corresponding to primary color components of a multicolored object are spatially multiplexed as a relief pattern on a surface of the hologram. A permanent optical density image of the spatially multiplexed fringe patterns is first formed on a panchromatic photographic plate. The plate is overcoated with a photoresist layer, back-exposed to contact-print the optical densit image onto the photoresist layer, after which the layer is processed to form the surface relief pattern.
