A HMD type multi-focus 3D display system is developed and experiment about satisfaction of eye accommodation is tested. Four LEDs(Light Emitting Diode) and a DMD are used to generate four parallax images at single eye and any mechanical part is not included in this system. The multi-focus means the ability of monocular depth cue to various depth levels. By achieving multi-focus function, we developed a 3D display system for only one eye, which can satisfy the accommodation to displayed virtual objects within defined depths. Therefore this proposed 3D display system has a possibility to solve the problem that the 3-dimensional image display system using only binocular disparity can induce the eye fatigue because of the mismatch between the accommodation of each eye and the convergence of two eyes. The accommodation of one eye is tested and a proof of the satisfaction of the accommodation is given as a result by using the proposed 3D display system. We could achieve a result that focus adjustment is possible at 4 step depths in sequence within 2m depth for only one eye.
