Three-dimensional internal back-projection system and method for using the same

Image Number 19 for United States Patent #8066378.

A projection system that projects coherent light rays from a coherent light (e.g., laser) source onto an inner surface of a three-dimensional projection surface is disclosed. A compact and low-power laser light image can thereby be formed and seen by an observer from outside the properly constructed three-dimensional projection surface. The three-dimensional projection surface thereby allows more accurate and interesting and useful projections of images of three-dimensional objects thereon. Examples of things that can be represented on such a surface are celestial bodies and planets like the Earth and anatomical organs. Special geometric and spatial correction is optionally applied to create the desired image onto a three-dimensional projection screen. Useful and entertaining information can also be displayed, optionally as dynamic and moving images, onto the projection screen as well.
