Patent ID: 7492513

Claim:
An autostereoscopic display apparatus for generating a three-dimensional image having four physiological depth perception cues of accommodation, convergence, binocular parallax and monocular movement parallax, the autostereoscopic display apparatus comprising: a collimated light source emitting a plurality of parallel light rays; and a spatial light modulator for receiving the plurality of parallel light rays from the collimated light source and for changing the colors and the intensities of the parallel light rays to predetermined values to form a plurality of independent and non-overlapping images; and a lens array having a plurality of lenses, each lens in the plurality of lenses for receiving one of the independent and non-overlapping images, each independent and non-overlapping image formed by the plurality of parallel light rays, each parallel light ray of the plurality of parallel light rays having a predetermined direction, intensity, and color at each point of receipt on each lens in the plurality of lenses and for redirecting the light rays to form a plurality of redirected light rays that generate the three-dimensional image having the four physiological depth perception cues.
