ABSTRACT:
A holographic terrain surface display system for simulating the visual scs available to a trainee pilot with respect to a terrain surface. The holographic terrain surface display system according to the present invention comprises a holographic film, having a plurality of holograms, illuminated by a laser light beam. The laser light beam is focused on one of the plurality of holograms to generate a real image of the terrain surface. The real image of the terrain surface is then projected onto a spherical front projection screen to be observed by the trainee pilot, at a remote location, through a closed circuit television system.
