Abstract

We propose a 3D display that allows multiple viewers to see 3D images from 360 degree of horizontal arc without wearing special glasses. It displays 3D images as reproductions of the light field around objects using a cylindrical parallax barrier and one-dimensional light source arrays. We have developed an experimental display system capable of displaying 3D color video images within a diameter and a height of 200 and 256 mm, respectively. Images are described by a resolution of 1254 pixels circularly, 256 pixels vertically, and refreshed at 30 Hz. The angular interval of the ray is less than 1 degree. In this case, viewers hardly perceive discreteness of parallax.
