Three-dimensional display system based on division multiplexing of viewer's entrance-pupil and display method thereof

摘要

Techniques and systems for presenting two or more perspective views to each eye of the viewer, through division multiplexing of the viewer's entrance-pupil. The system (300, 600, 900, 2000, 2100) is constituted by a selective-aperture array (120, 320, 920, 1120, 2020, 2120, 2220, 2520, 2520') with each aperture being transparent only to light beams with some special characteristics, at least one display screen (110, 310, 410, 510, 510', 510'', 610, 610', 910, 910', 1110, 2010, 2110, 2210, 2510, 2510') for optical information presentation, and other optional elements. The optical message on at least one display screen (110, 310, 410, 510, 510', 510'', 610, 610', 910, 910', 1110, 2010, 2110, 2210, 2510, 2510') propagates to the selective-aperture array (120, 320, 920, 1120, 2020, 2120, 2220, 2520, 2520') directly, or be directed to the selective-aperture array (120, 320, 920, 1120, 2020, 2120, 2220, 2520, 2520') or the eye of the viewer by other optional elements. Through selective filtering by the apertures with temporal filtering characteristics or exclusive filtering characteristics, multiple perspective views get presented to an eye of the viewer through the selective-aperture array (120, 320, 920, 1120, 2020, 2120, 2220, 2520, 2520'). Light rays different perspective views superimpose into real spatial light spots that the eye can focus on naturally, resulting in overcoming of the accommodation-convergence conflict.
