  • Patent number: 6593957
    Abstract: Autostereoscopic image displays provide highly realistic three-dimensional images to one or a plurality of viewers without the need for wearable appliances. In some embodiments, the images are viewed through a beamsplitter, while in other embodiments the viewer observes the images on a display screen. A viewer-tracking system monitors the viewer's movements and directs each image of a stereopair to the proper eye of the viewer. In some embodiments, the stereoimages are kept independent and separately directed through differential polarization. In other embodiments, this is accomplished through selective intensity modulation.
