ABSTRACT:
Multiple layers or holographic exposures and methods for preparing multiple layers of holographic exposures are described. The multiple layers of holographic exposure combine to form holographic stacks and are fabricated from layers of exposed and processed photosensitive recording films, each of which has at least one independently recorded hologram. The holographic stacks are useful for providing wide bandwidth holograms and holograms having superimposed images.
