Abstract: A light system that may project virtual content onto surfaces of a room. The system may include one or more low-resolution light-emitting diode (LED) projectors for emitting light representing low-resolution virtual content, and a high-resolution LED projector for emitting light representing high-resolution virtual content. The high-resolution projector may be used to project a 2D image of augmented or virtual reality content being viewed by a person in a room using a device such as a headset or glasses onto a surface of the room so that other persons in the room can view a representation of what the person using the device is seeing. The low-resolution projector(s) may project low-resolution images onto other surfaces in the room, for example the walls and ceiling. The system may also be configured to emit diffuse light to illuminate a room when not emitting light representing virtual content.

Abstract: A mixed reality direct retinal projector system that may include a headset that uses a reflective holographic combiner to direct light from a light engine into an eye box corresponding to a user's eye. The light engine may include light sources coupled to projectors that independently project light to the holographic combiner from different projection points. The light sources may be in a unit separate from the headset that may be carried on a user's hip, or otherwise carried or worn separately from the headset. Each projector may include a collimating and focusing element, an active focusing element, and a two-axis scanning mirror to project light from a respective light source to the holographic combiner. The holographic combiner may be recorded with a series of point to point holograms; each projector interacts with multiple holograms to project light onto multiple locations in the eye box.

Abstract: Point to point transmission holograms are used to provide a scene camera for an augmented reality glasses display system. A glass or plastic substrate acts as spectacle style lens. A holographic medium is applied to a surface of the substrate, within which is recorded a series of point to point transmission holograms. The construction points of the holograms are arranged at the eye and at the pupil of a camera placed, ideally, to the temple side of the user's eye. The recorded transmission holograms act by diffracting a portion of the light from the scene surrounding the user that is heading for the user's eye towards the scene camera. The hologram efficiency is balanced so that the user is still able to see the surrounding scene. The perspective of the view seen by the scene camera is substantially identical to that seen by the user through the lens.

Abstract: Methods and systems for a virtual and/or augmented reality device may include a light emitting device that includes one or more light emitting elements configured to generate collimated light beams. A scanning mirror may include one or more microelectromechanical systems (MEMS) mirrors. Each MEMS mirror of the scanning mirror may be configured to dynamically tilt in at least one of two orthogonal degrees of freedom to raster scan the light beams over multiple angles corresponding to a field of view of an image. A curved mirror may include curves in two orthogonal directions configured to reflect the collimated light beams from the scanning mirror into a subject's eye in proximity to the curved mirror to form a virtual image. The curved mirror may allow external light to pass through, thus allowing the virtual image to be combined with a real image to provide an augmented reality.

Abstract: An augmented reality headset may include a reflective holographic combiner to direct light from a light engine into a user's eye while also transmitting light from the environment. The combiner and engine may be arranged to project light fields with different fields of view and resolution to match the visual acuity of the eye. The combiner may be recorded with a series of point to point holograms; one projection point interacts with multiple holograms to project light onto multiple eye box points. The engine may include a laser diode array, a distribution waveguide, scanning mirrors, and layered waveguides that perform pupil expansion and that emit wide beams of light through foveal projection points and narrower beams of light through peripheral projection points. The light engine may include focusing elements to focus the beams such that, once reflected by the holographic combiner, the light is substantially collimated.

Abstract: A head-mounted device may include one or more adjustable lens elements. The adjustable lens element may include a transparent substrate, a collapsible wall that forms an enclosed perimeter on the transparent substrate, and a flexible membrane on the collapsible wall that together define an interior volume. The interior volume may be filled with a fluid. The adjustable lens element may include a lens shaping component that applies a force to the collapsible wall to adjust a height of the collapsible wall relative to the transparent substrate, which in turn may be used to adjust the shape of the flexible membrane and thus the lens power of the lens element. The collapsible wall may have bellows that allow the collapsible wall to fold on itself when compressed, thereby minimizing unintended lateral movement of the collapsible wall.
