Abstract
Three types of multi-focus(MF) 3D display are developed and possibility about monocular depth cue is tested. The multi-focus means the ability of monocular depth cue to various depth levels. By achieving multi-focus function, we developed 3D display system for each eye, which can satisfy accommodation to displayed virtual objects within defined depth. The first MF 3D display is developed via laser scanning method, the second MF 3D display uses LED array for light source, and the third MF 3D display uses slated LED array for full parallax monocular depth cue. The full parallax MF 3D display system gives omnidirectional focus effect. The proposed 3D display systems have a possibility of solving eye fatigue problem that comes from the mismatch between the accommodation of each eye and the convergence of two eyes. The monocular accommodation is tested and a proof of the satisfaction of the full parallax accommodation is given as a result of the proposed full parallax MF 3D display system. We achieved a result that omni-directional focus adjustment is possible via parallax images.
