Pixel patterns for voxels in contact-type three dimensional imaging systems

Abstract

A three dimensional image (3-D) is synthesized with the use of voxels with known coordinates. Each of these voxels has a corresponding pixel pattern in the display panel. The pattern is found in the optical geometry of the defined viewing zone in contact-type 3-D imaging systems based on a point light source array by assuming that each of the voxels can be seen at any place in the zone. This geometry provides that voxels are aligned in known planes parallel to the array plane. Since each of these voxels is made of rays from specific point light sources, which pass specific pixels in the display panel, the pixel pattern for each voxel is determined as that of the pixels that enable the sources to be seen in the viewing zone through them. The resulting pixel pattern creates a good 3-D image.
