Three-Dimensional Light Field Display with Overlaid Projection

In the three-dimensional light field display, the quality of the 3D image depends on the resolution of the display device which is part of the system. A single LCD or projector device has been used as a display to construct the conventional 3D display. However, it is difficult to display the high quality 3D image by the system constructed of a single display device, because the resolution of the display device is limited. In order to solve this problem, we proposed the 3D display system with overlaid projection. The system consists of multiple projectors, a lenticular lens array sheet, and a condenser lens. In this system, light rays from a projector pass through a lenticular lens sheet and condenser lens and are observed directly. This paper describes the principle of proposed 3D display system, and the experimental results.
