Paper Abstract

We propose an omnidirectional three-dimensional (3D) display system for multiple users as an improved version of our previous thin natural 3D display based on the ray reconstruction method. This is a tool for communication around a 3D image among a small number of people. It is a flatbed-type autostereoscopic 3D display system. It consists of some flat panel displays and some holographic lens array sheets. Its notable feature is the ability to display natural 3D images which are visible to multiple viewers at the same time. Moreover, 3D real images float over the proposed flatbed-type display. Thus, proposed display allows two or more people surrounding it to simultaneously observe floating 3D images from their own viewpoints. The prototype display consists of two DMD (digital micromirror device) projectors and two holographic lens array sheets. The number of the 3D pixels about one holographic lens array sheet is 48×96. Reconstructed 3D images are superimposed over the display. Therefore, this can display a floating 3D image which size is 108 mm ×80.8 mm ×80.8 mm. This paper describes a flatbed-type omnidirectional 3D display system, and also describes the experimental results.
