  • Freeform nanostructured surface for virtual and augmented reality near eye display
    Patent number: 10371951
    Abstract: A near eye display includes at least one of a combiner, a secondary mirror, and a waveguide having a freeform nanostructured surface. The freeform nanostructured surface encompasses a freeform surface, a nanostructured surface or a combination of both the freeform surface and the nanostructured surface. The freeform nanostructured surface can be incorporated into a combiner or a secondary mirror in the near eye display in a compact folded geometry, wherein an anamorphic or freeform optic can be optically intermediate an image source and the freeform nanostructured surface. The nanostructured surface can include a meta-grating operable across the visible spectrum. The meta-grating includes meta-atoms configured to provide a given efficiency at the desired wavelengths in reflection.
