Abstract
Abstract A method and apparatus for display of a three dimensional virtual image is provided. The present invention allows one or more objects, real images and virtual images to be displayed at one or more of an arbitrary number of depth levels along a viewer's line of sight. The present invention uses a plurality of beam splitters organized as an optical labyrinth to combine a images with the proper perspective and parallax to result in a three dimensional image.
