Three-dimensional electro-floating display system using an integral imaging method.
A new-type of three-dimensional (3D) display system based on two different techniques, image floating and integral imaging, is proposed. The image floating is an antiquated 3D display technique, in which a large convex lens or a concave mirror is used to display the image of a real object to observer. The electro-floating system, which does not use a real object, requires a volumetric display part in order to present 3D moving pictures. Integral imaging is an autostereoscopic technique consisting of a lens array and a two-dimensional display device. The integral imaging method can be adapted for use in an electro-floating display system because the integrated image has volumetric characteristics within the viewing angle. The proposed system combines the merits of the two techniques such as an impressive feel of depth and the facility to assemble. In this paper, the viewing characteristics of the two techniques are defined and analyzed for the optimal design of the proposed system. The basic experiments for assembling the proposed system were performed and the results are presented. The proposed system can be successfully applied to many 3D applications such as 3D television.
