360 degree tabletop electronic holographic display.
We demonstrate a tabletop holographic display system for simultaneously serving continuous parallax 3.2 inch 360 degree three dimensional holographic image content to multiple observers at a 45 degree oblique viewing circumference. To achieve this, localized viewing windows are to be seamlessly generated on the 360 degree viewing circumference. In the proposed system, four synchronized high speed digital micro mirror displays are optically configured to comprise a single 2 by 2 multi vision panel that enables size enlargement and time division multiplexing of holographic image content. Also, a specially designed optical image delivery sub system that is composed of parabolic mirrors and an aspheric lens is designed as an essential part for achieving an enlarged 3.2 inch holographic image and a large 45 degree oblique viewing angle without visual distortion.
