An Aerial Autostereoscopic Display Using Time-Division Multiplexing Parallax Barrier

摘要

A high definition aerial stereoscopic display is realized by combining a convex lens and time-division parallax barrier. The proposed system attains a wide stereoscopic viewing zone and little crosstalk without any moving parts. To show an undistorted aerial image in the proposed system, optical distortion by the lens should be corrected, which is realized by real-time optical simulation and texture mapping. Crosstalk and the effect of distortion correction are evaluated with a prototype system. The frame rate of the system is tested under different conditions using different graphic cards.
