Abstract
Optical viewing system for producing a simulated three dimensional image. The system includes electronic equipment for displaying an image on a first electronic display device. Additional electronic equipment is provided for displaying an image on at least one second display device. The at least one second electronic display device is a substantially transparent display device, whereby an observer can view through transparent areas of the second electronic display device. The first and second electronic display devices are located at different, predetermined locations along an optical viewing path such that the image displayed by the first electronic display device is projected through the second electronic display device. The first electronic display device includes an image projector and the second electronic display device includes a controllable pixel display spaced therefrom. The controllable pixel display is comprised of a positive pixel display panel having a field of pixel elements which are controllably illuminated. The controllable pixel display is substantially transparent such that the image produced by the controllable pixel display is overlaid upon the image produced …
