ABSTRACT:
A method and apparatus for the holographic storage of terrain data on a hgraphic recording material. The holographic storage apparatus includes a camera, positioned above a terrain surface, for recording on a photographic film a plurality of photographic images of a matrix of perspective points of a terrain surface. A laser gives rise to an object laser light beam which is directed onto, and is reflected from, the photographic film; and, a reference laser light beam which is directed onto the holographic recording material. An object transform lens directs the reflected object laser light beam onto the holographic recording material to form, when combined with the reference laser light beam, a plurality of holograms, with each of the holograms based on a photograph taken from one of the matrix of perspective points above the terrain surface.
