Patent ID: 8334889

Claim:
An auto stereoscopic integral holographic display, comprising: a dynamic refreshable holographic recording material held in a stationary mount to present a stationary direct-view display to an audience; a memory; hogel data stored in said memory, said hogel data encoded using integral imaging from multiple views of a scene, said hogel data representing a temporal sequence of multiple holograms for presentation to the audience at a refresh rate; a pulsed laser that produces a coherent pulsed beam at a repetition rate to support presentation of the holograms at the refresh rate; a beam splitter that splits the coherent pulsed beam into an object beam and a reference beam; a spatial light modulator (SLM), said hogel data loaded into said SLM as an image to spatially modulate the amplitude of the object beam with the hogel data, said hogel data loaded into said SLM at a load rate to support presentation of the holograms at the refresh rate; a beam steering mechanism that steers the modulated object beam and the reference beam relative to the stationary holographic recording material to interfere at the material and write successive hogels at different locations on the material to record the holograms at the refresh rate; a reading source that directs a reading beam onto the holographic recording material, said reading beam diffracted by the hologram to produce a diffracted beam that presents the auto stereoscopic integral hologram to the audience, said hologram being refreshed at said refresh rate; and control electronics that synchronize the pulsed laser, beam steering mechanism and SLM.
