We performed a comparative analysis for multi-view autostereoscopic display and horizontal parallax only integral
imaging display. The spatio-angular ray distribution reconstructed by two technologies is calculated and used as a metric
to evaluate the three-dimensional image reconstruction quality. Based on the ray reconstruction characteristics, we also
propose a method to convert a set of perspective images for multi-view displays to a set of orthographic images for
integral imaging display.
Three-dimensional holographic system using active shutters for head mounted display application is proposed.
Conventional three-dimensional head mounted display suffers from eye-fatigue since it only provides binocular
disparity, not monocular depth cues like accommodation. The proposed method presents two holograms of a 3D scene to
corresponding eyes using active shutters. Since a holography delivered to each eye has full three-dimensional
information, not only the binocular depth cues but also monocular depth cues are presented, eliminating eye-fatigue. The
application to the head mounted display also greatly relaxes the viewing angle requirement that is one of the main issues
of the conventional holographic displays. In presentation, the proposed optical system will be explained in detail with
