- 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.
