Autostereoscopic display system
Abstract:
An autostereoscopic display system comprised of an array of vertically oriented narrow light sources and a spatial light modulator, (SLM), disposed between the lights and viewers, whereby light rays originating from selected lights pass through the SLM in direct lines to viewers eyes The lights are sequentially flashed, sending light through the SLM where selected full height narrow vertical picture lines, VPL's, are made briefly transmissive while the remainder of the SLM remains dark, projecting vertically oriented sheets of light through selected VPL's toward selected eyes. The light sheets are sufficiently narrow as to enter a left or right eye but not both, The process rapidly repeats for all VPL's and all array lights, alternating between right/left SLM scenes each projected into appropriately selected eyes resulting in a 3D image.
