Abstract

A device for time-based multiplexing of a projection of a three-dimensional FIG. 1 image to increase its resolution includes a two-dimensional display comprising an array of pixels. An array of optical elements is placed in front of the pixels. The optical elements are structured to refract and configure into multiple parallel light beams, in a plurality of angles, light emitted from the pixels. An array of adjustable light deflecting devices is mounted in front of the pixels. Each of the adjustable light deflecting devices is structured to deflect the light emitted by the pixels. At least one controller is configured to (1) vary at least one of the intensity or color of light emitted by each of the pixels according to three-dimensional information set for display of a three dimensional image; and (2) change a deflection angle of the light deflecting devices during a period of image integration of the human visual system.
