Paper Abstract

Tabletop 3D display is a device that can provide several position-dependent 3D scenes in a circular viewing zone to viewers. In this paper, a kind of new method could provide a tabletop 3D display which was designed with the pixelated nano-gratings in pixels of the image and fabricated to modulate the collimated illumination light and project multiple converged transmitted light beams into each circular viewing zone. In this monochromatic tabletop display prototype, several viewing points were achieved in a circular viewing zone. The minimum angular separation set in this prototype between adjacent viewing points was 1 degree and the angular divergence of each viewing angle was measured and calculate as 0.958 degree. In this paper, the resolution of the generated 3D image at each view was 640×360 pixels. Using the proposed technology, the 360-degree viewable 3D display system can be constructed easily with multiple viewing points either evenly or unevenly distributed in the viewing zone. In addition, several artificially generated 3D image can be mixed well with the real physical objects placed on the tabletop screen, suggesting a natural mixed-reality environment provided by the proposed system. The potential applications of the proposed tabletop 3D display system are very comprehensive including desktop conference, tables games, trade show display, and sandtable.
