Claim:
1. A display system, comprising: a display controller providing a set of three or more images; a projector projecting a light beam that is a combination of the three or more images; and a screen assembly displaying the three or more images on three or more screens positioned at three or more differing focal planes or in three or more view zones to provide an autostereoscopic display, wherein the projected light beam comprises a number of multiplexed beams each associated with a differing optical angular momentum (OAM) mode, wherein each of the multiplexed beams has a wavefront shaped as a helical vortex with a pitch differing from other ones of the multiplexed beams, wherein each of the OAM modes is associated with a differing one of the three or more images, wherein the projector comprises a spatial light modulator (SLM) displaying a combination computer-generated hologram, wherein the combination computer-generated hologram is formed by combining a set of computer-generated holograms each representing one of the three or more images, and wherein the projector further includes a light source directing a collimated light beam onto the SLM during the displaying of the combination computer-generated hologram thereby producing the projected light beam.
