Abstract

Approaches to displaying 3D images (e.g. stereoscopic display, volumetric system and integral photography.) currently used can not present real 3D images for users. Holography is an intriguing technique for visualizing 3D objects because it is the only 3D display technology known today that is capable of creating the most authentic illusion of observing volumetric objects by the naked eyes, therefore, the visualization of 3D models using a kind of holographic display is an appealing task. In this paper, a new approach to 3D Terrain Model display is proposed, and in which the computer-generated hologram (CGH) is used in the holographic stereography instead of recording a hologram by interfering coherent light in conventional holography. An example in which the terrain display using holographic stereography is preliminarily simulated with computer, however, it shows that the proposed approach is theoretically feasible and promising.
