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.

First Claim:
Show all 28 claims
I claim:     1. A display comprising:
  • a first image source;
  • a second image source;
  • a first beam splitter positioned such that a first image from said first image source is reflected by said first beam splitter and a second image from said second image source is transmitted through said first beam splitter so as to provide a third image as a composite image of said first and second images;
  • a third image source;
  • a second beam splitter positioned such that said third image is reflected by said second beam splitter and a fourth image from said third image source is transmitted through said second beam splitter so as to provide fifth image as a composite image of said third and fourth images.
