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: 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 a lens module with a least one adjustable lens. The head-mounted device may be wirelessly paired to an electronic device such as a cellular telephone, watch, laptop computer, etc. To correct for presbyopia, the optical power of adjustable lenses in a head-mounted device may be adjusted when the user is viewing a close object. To allow for intelligent adjustments of the adjustable lenses while minimizing power consumption in the head-mounted device, the head-mounted device may receive sensor data and/or focal point change instructions from a paired electronic device. The paired electronic device may detect a trigger, analyze the user's attention to the paired electronic device, and send focal point change instructions to the head-mounted device based on the obtained information.

Abstract: A lens module may include a first lens element, a lens shaping structure that is coupled to the first lens element, and a plurality of actuators that are configured to adjust a position of the lens shaping structure to adjust the first lens element. The lens module may also include a second lens element and a fluid-filled chamber between the first and second lens elements. To allow dynamic adjustments of the second lens element without requiring additional actuators, the second lens element may be a semi-rigid lens element. When the actuators adjust the curvature of the first lens element, the gauge pressure applied to the second lens element is changed. This causes a change in curvature of the second lens element. The actuators may therefore adjust the curvature of both the first and second lens elements even though none of the actuators are attached to the second lens element.

Abstract: An electronic device may include a display module that generates image light and an optical system that redirects the light towards an eye box. The optical system may have first hologram structures that replicate the light over multiple output angles onto second hologram structures. The second hologram structures may focus the replicated light onto the eye box. If desired, the device may include an image sensor. The first and second hologram structures may include transmission and/or reflection holograms. The optical system may redirect a first portion of the light to the eye box and a second portion of the light to the sensor. The sensor may generate image data based on the second portion of the light. Control circuitry may compensate for distortions in the first portion of the light by performing feedback adjustments to the display module based on distortions in the image data.
