    摘要： Depth-sensing apparatus includes a laser, which emits pulses of optical radiation toward a scene. One or more detectors 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. A scanner scans the pulses of optical radiation across the scene along successive parallel scan lines of a raster. Control and processing circuitry drives the laser to emit a succession of output sequences of the pulses with different, respective temporal spacings between the pulses within the output sequences in the succession, and matches the times of arrival of the signals due to the optical radiation reflected from the points in at least two adjacent scan lines in the raster to the temporal spacings of the output sequences in order to find respective times of flight for the points in the scene.

    摘要： A system such as a vehicle system, building, or electrical equipment may be provided with one or more optical components. The optical components may include a near-infrared camera or other components that operate at near-infrared wavelengths. A visible-light-reflecting-and-infrared-light-transmitting layer may overlap the optical component. This overlapping layer may have first and second index-matched layers and an interposed textured layer. The textured layer may be a thin-film interference filter or other coating that is configured to reflect visible light while transmitting infrared light. The transmitted infrared light may pass to the optical component with minimal wavefront distortion due to the index matching of the first and second layers. The texture of the textured layer may cause visible light to reflect diffusely and thereby provide the visible-light-reflecting-and-infrared-light-transmitting layer with a matte appearance.

    摘要： A device for capturing an image includes an image sensor having a plurality of sensing elements and a control circuit. The control circuit is configured to receive a first group of image signals from a first portion of the plurality of sensing elements using at least a first binned read mode; receive a second group of image signals from a second portion of the plurality of sensing elements using a non-binned read mode; generate a first image based on at least the first group of image signals and the second group of image signals; and generate a second image based on the second group of image signals.

    摘要： A light-based device may provide images and other light output to a user and may gather user input. The device may include a light guide array formed from a bundle of fibers. The light guide array may have an entrance surface that receives light emitted by a light-emitting device. The light-emitting device may include one or more light-emitting diodes and may be a display having an array of pixels. Light from the light-emitting device may be conveyed from the entrance surface to the exit surface by the light guide array. The exit surface of the light guide array may have a compound curvature. Optical structures may be formed over the exit surface. The light-based device may form light-field display, may form a touch sensor, may form a controller, and may form other structures.
