Abstract: An HMD device includes a display panel and an x-prism beamsplitter disposed along a first axis between the display panel and an expected position of an eye of a user. The x-prism beamsplitter directs a first light beam in a first direction from the display panel to the eye along the first axis, directs a second light beam in a second direction along a second axis substantially perpendicular to the first axis, and directs a third light beam in the second direction along the second axis, wherein the second light beam is representative of the first light beam and the third light beam is representative of a reflection of the first light beam off of the eye. The HMD device further includes an imaging camera to capture a composite image comprising a combination of both a representation of the second light beam and a representation of the third light beam.

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.
