ABSTRACT:
Holographic techniques are utilized to create a lens or magnifying effect in a surface film. This surface film deflects the light rays so that they leave the film at a much different angle then they arrive at the film. Since holographically produced lenses are more efficient in the transmission mode at angles deviating substantially from near normal angles of incidence, the images to be displayed for the left eye of a viewer are substantially displaced from those images for the right eye of the viewer as opposed to the prior art presentation of holographic stereoscopic displays which positioned all of the left eye images immediately adjacent all of the right eye images for a given segment of the total picture.
