  • Patent number: 6808268
    Abstract: An aerial projection system and method having a housing for positioning low cost optical elements capable of generating a three dimensional aerial images at video rates without reflected artifacts or visible display of the display screen. A method for generating the display images is based on a set of rules that eliminate boundary transgressions and maximizes the illusion of a three dimensional aerial image. An optional second display is a transparent imaging panel that acts selectively as a light valve, as a display platform for special effects or for providing the appearance of linear motion towards or away from the observer. An optional third display, also a transparent imaging panel, may be used as a background display device for displaying video rate images that are not projected aerial images.
