Abstract: An electronic device may have back-to-back displays. A user-facing display may have microlenses, tunable lens structures, holograms, lasers, and other structures for displaying images in multiple eye boxes while the electronic device is being worn on the head of a user. In some configurations, a switchable diffuser may be incorporated into the user-facing display. In one mode, the switchable diffuser allows microlenses of the pixels of the user-facing display to provide images to eye boxes in which images from the display are viewable. In another mode, the switchable diffuser diffuses light from the pixels so that the user-facing display may be used while the device is being held in the hand of the user.

Abstract: Some embodiments include a fixed chassis structure and a moveable carriage body carrying one or more lenses. The fixed chassis structure includes a magnetic friction track. The moveable carriage body carries one or more lenses. An electrically-controllable magnet is mounted to the moveable carriage body for generating a magnetic attraction force between the magnet and the magnetic friction track. The moveable carriage body is movably mounted to the chassis to allow movement along an optical axis through the one or more lenses. An inertial actuator is mounted to the moveable carriage body in an alignment such that the axis of motion of the actuator is parallel to the optical axis through the one or more lenses. The moveable carriage body is held in place with respect to the at least one allowed degree of freedom by one or more friction forces resulting from the magnetic attraction force.

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: 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.

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: Embodiments described include a system comprising a position sensing device (PSD) and a light source. The light source is configured to, by passing one or more light beams through the PSD, cause one or more electrical currents to flow through the PSD. The system further comprises a processor, configured to (i) in response to the electrical currents, ascertain an amount of power that is delivered by the light source, and (ii) in response to the amount of power exceeding a threshold amount of power, inhibit the light source from further operation. Other embodiments are also described.
