Paper Abstract

A new type of holographic screen used to display projected 3-dimensional (3D) images with large viewing angle and relatively high brightness is presented. The screen is 2-dimensional hexagonal lattice relief in micron-scale lattice period, fabricated in plastic sheet using holographic technique and pattern replication method so that the fabrication of the screen is fast and cost effective and large-size screen can be obtained. Theoretical analysis and experimental results demonstrate that larger lattice period generates more diffracted rays thus provides larger viewing anlge and brighter image. 45° horizontal and 30° vertical viewing anlges have been achieved and the images with parallax have been observed. The screen has the potential of being applied for 3D holographic movie display and 3D art exhibition.
