  • Optics display system with dynamic zone plate capability
    Patent number: 9857593
    Abstract: Natural-scene light is polarized so the light exiting the polarizer and entering a glass assembly has a first polarization. Light having a second polarization substantially orthogonal to the first polarization is launched into the glass assembly and directed normal to the glass assembly and into a zone plate assembly, along with the natural-scene light. A first plurality of electric fields is established in the zone assembly to form at least one zone plate that modulates the launched light without modulating the natural-scene light. The first plurality of electric fields is disestablished and a second plurality of electric fields is established in the zone plate assembly to reposition the at least one zone plate in the liquid crystal plate. Disestablishment and establishment of electric fields is repeated at a sufficient rate so that an image defined by a number of pixel spots formed on a retina is perceived by a viewer.
