Full parallax multifocus three-dimensional display using a slanted light source array

Abstract

A new multifocus three-dimensional display which gives full parallax monocular depth cue and omni-directional focus is developed with the least parallax images. The key factor of this display system is a slanted array of light-emitting diode light source, not a horizontal array. In this system, defocus effects are experimentally achieved and the monocular focus effect is tested by four parallax images and even two parallax images. The full parallax multifocus three-dimensional display is more applicable to monocular or binocular augmented reality three-dimensional display in the modification to a see-through type.
