    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: An optical transmission device (30, 80, 90) includes a waveguide (50, 92) including a transparent medium (52) having mutually-parallel first and second surfaces arranged so that light propagates within the waveguide by internal reflection between the first and second surfaces. At least one light source (58) is configured to inject coherent light into the waveguide. A first array of diffractive structures (64, 96) is applied to the waveguide and configured to couple respective beams (66) of the coherent light out through the first surface of the waveguide. The device includes a second array of tunable optical phase modulators (70), which are overlaid on respective ones of the diffractive structures in the first array and are configured to apply different respective phase shifts to the respective beams, thereby modulating a far-field light pattern (31) formed by interference between the beams.

    Abstract: A Predictive, Foveated Virtual Reality System may capture views of the world around a user using multiple resolutions. The Predictive, Foveated Virtual Reality System may include one or more cameras configured to capture lower resolution image data for a peripheral field of view while capturing higher resolution image data for a narrow field of view corresponding to a user's line of sight. Additionally, the Predictive, Foveated Virtual Reality System may also include one or more sensors or other mechanisms, such as gaze tracking modules or accelerometers, to detect or track motion. A Predictive, Foveated Virtual Reality System may also predict, based on a user's head and eye motion, the user's future line of sight and may capture image data corresponding to a predicted line of sight. When the user subsequently looks in that direction the system may display the previously captured (and augmented) view.

    IPC: G02B27/01

    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: Depth-sensing apparatus (20) includes a laser (28), which is configured to emit pulses of optical radiation toward a scene, and one or more detectors (40), which are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. Control and processing circuitry (44, 38) is coupled to drive the laser to emit a sequence of the pulses in a predefined temporal pattern that specifies irregular intervals between the pulses in the sequence, and to correlate the output signals with the temporal pattern in order to find respective times of flight for the points in the scene.
