Abstract: A near-eye display system includes a display panel, a beam steering assembly facing the display panel, a display controller, and a beam steering controller. The beam steering assembly imparts one of a plurality of net deflection angles to incident light. The display controller drives the display panel to display a sequence of images, and the beam steering controller controls the beam steering assembly to impart a different net deflection angle for each displayed image of the sequence. The sequence of images, when displayed within the visual perception interval, may be perceived as a single image having a resolution greater than the resolution of the display panel or having larger apparent pixel sizes that conceal the black space between pixels of the display, or the sequence of images may represent a lightfield with the angular information represented in the net deflection angles imparted into the images as they are projected.

Abstract: An optical apparatus for a head wearable display includes a lightguide, in-coupling holograms, and an out-coupling optical element. The lightguide includes an in-coupling region for receiving display light into the lightguide, an out-coupling region for emitting the display light out of the lightguide, and a relay region for guiding a path of the display light from the in-coupling region to the out-coupling region. A first of the in-coupling holograms is disposed at the in-coupling region to redirect the path of the display light by a first angle. A second of the in-coupling holograms is disposed across from the first in-coupling hologram at the in-coupling region to redirect the path of the display light by a second angle such that the path of the display light enters a total internal reflection condition in the relay region after redirection by the first and second in-coupling holograms.
