  • Patent number: 5198928
    Abstract: A binocular, stereoscopic helmet visor display is described, wherein a polarization x-prism is used to separate the left eye imagery from the right eye imagery when each channel has a unique polarization. Separate image sources generate the left and right eye imagery, and the respective left and right image light is passed through polarizers so that the respective left and right image light is of opposite polarizations. The polarized left and right image light is combined through a common optical relay and passed to the x-prism which separates the polarized light, sending the "p" polarized light out one channel to one eye, and the "s" polarized light out the other channel to the other eye. Once the channels are separated, the images are projected to the observer's eyes.
