Three-dimensional display using a modified two-dimensional array and its demonstration

Abstract

A new 3D display technique is proposed which offers faithful 3D images. A number of horizontal parallax images are displayed by a number of afocal imaging systems aligned in a modified two-dimensional array, and a common vertical viewing zone is produced by a vertical diffuser. The technique does not require wearing any 3D glasses and several persons can observe 3D images simultaneously. Color and animated 3D images can be displayed. Observers can percept 3D images with binocular disparity, ocular vergence, motion parallax, and accommodation. There are two types of configurations to display multiple parallax images; image-level multiplexing and pixel-level multiplexing. A prototype having 64 parallaxes is constructed based on the former configuration.
