Abstract
A system for presenting stereoscopic images to a viewer includes a screen for presenting first and second images and a plurality of louvers for isolating the images for viewers located back from the screen along predetermined sight lines. In a first embodiment, a pair of stereoscopic images are presented simultaneously on co-planar screens, and fixed isolation louvers isolate the images for a viewer positioned along a center line from the viewing enclosure. In a second embodiment, the stereoscopic images are presented sequentially on a common screen, and movable louvers are provided for isolating the images first from the right eye and then from the left eye. In both cases, viewers may experience three-dimensional images without having to wear glasses or goggles and without having to come up immediately to the viewing device.
