    Abstract: Mapping apparatus includes a transmitter, which is configured to emit, in alternation, at least two beams comprising pulses of light along respective beam axes that are mutually offset transversely relative to a scan line direction of a raster pattern. A scanner is configured to scan the two or more beams in the raster pattern over a scene. A receiver is configured to receive the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from points in the scene. A processor is coupled to process the output of the receiver so as to generate a 3D map of the scene.

    Abstract: A user interface method, including presenting by a computer executing a user interface, multiple interactive items on a display. A first sequence of images is captured indicating a position in space of a hand of a user in proximity to the display, and responsively to the position, one of the interactive items is associated with the hand. After associating the item, a second sequence of images is captured indicating a movement of the hand, and responsively to the movement, a size of the one of the items is changed on the display.

    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: Image projection apparatus includes an image generating assembly, which is configured to project a sequence of line images extending in a first direction. A scanning mirror is positioned to receive and to reflect the line images while rotating about a mirror axis parallel to the first direction. A pupil expander has an edge positioned to receive the line images reflected by the scanning mirror and a face extending in a second direction non-parallel to the first direction and to the edge, and which is configured to direct simultaneously through the face multiple, parallel replicas of the expanded line images arrayed along the second direction.

    Abstract: An optical device includes a transmitter, which emits a beam of optical radiation, and a receiver, which includes a detector configured to output a signal in response to the optical radiation. An active area of the detector has a first dimension along a first axis and a second dimension, which is less than the first dimension, along a second axis perpendicular to the first axis. An anamorphic lens, which collects and focuses the optical radiation onto the active area of the detector, has a first focal length in a first plane containing the first axis and a second focal length, greater than the first focal length, in a second plane containing the second axis. A scanner scans the beam across a target scene in a scan direction that is aligned with the first axis, and directs the optical radiation that is reflected from the target scene toward the receiver.

    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.
