Paper Abstract

We propose a multi-projection based multi-view 3D display system using an optical waveguide. The images from the projection units with the angle satisfying the total internal reflection (TIR) condition are incident on the waveguide and experience multiple reflections at the interface by the TIR. As a result of the multiple reflections in the waveguide, the projection distance in horizontal direction is effectively reduced to the thickness of the waveguide, and it is possible to implement the compact projection display system. By aligning the projection array in the entrance part of the waveguide, the multi-view 3D display system based on the multiple projectors with the minimized structure is realized. Viewing zones are generated by combining the waveguide projection system, a vertical diffuser, and a Fresnel lens. In the experimental setup, the feasibility of the proposed method is verified and a ten-view 3D display system with compact size in projection space is implemented.
