  • Patent number: 11442306
    Abstract: An optical display system includes an information display (image-generating) component, a polarization rotator, a polarization dependent optical element, an input holographic coupler, a light guide and an output holographic coupler. By controlling the polarization of the displayed light through the polarization rotator, the polarization dependent optical element changes the viewable content to different distances from the viewer. This enables the generation of a proper light field which will then be coupled into the light guide through the input holographic coupler, and finally go through the output holographic coupler to a user's eye.
