Abstract:
A display device for producing a three-dimensional image, comprising:a viewing area having a front, a back and a depth;a rotatable spiral screen developed by at least two radii, said screen having a central axis disposed within said viewing area, said radii disposed perpendicular to said central axis, said radii being disposed a distance from one another along said central axis, said screen having a front surface and a rear surface, said front surface of said spiral screen facing said front of said viewing area, said spiral screen rotatable along its central axis;means to form an image of a three dimensional object by the emission of light from the surface of said spiral screen using energy from said screen; andmeans to rapidly rotate said spiral screen within said viewing area wherein said image is viewable from the front of said viewing area and said image is produced relative to its position within the depth of said viewing area.
