Abstract: An optical sensing device includes a light source, which is configured to emit one or more beams of light pulses at respective angles toward a target scene. An array of sensing elements is configured to output signals in response to incidence of photons on the sensing elements. Light collection optics are configured to image the target scene onto the array. Control circuitry is coupled to actuate the sensing elements only in one or more selected regions of the array, each selected region containing a respective set of the sensing elements in a part of the array onto which the light collection optics image a corresponding area of the target scene that is illuminated by the one of the beams, and to adjust a membership of the respective set responsively to a distance of the corresponding area from the device.

Abstract: Optical apparatus includes a projector, which directs a sequence of pulses of radiation toward a scene so as to form one or more lines of the radiation on the scene. A receiver includes an array of single-photon detectors, which output, in response to the radiation that is incident thereon, signals indicative of a time-of-flight of the pulses from the projector to the receiver via the points in the scene, and collection optics, which form an image the scene on the array, including the one or more lines of the radiation, such that each single-photon detector receives the radiation reflected from a corresponding point in the scene. A processor receives the signals output by the sensing elements, and derives depth coordinates of the points in the scene from both the time-of-flight of the pulses and triangulation of the one or more lines in the image.

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.

Abstract: Imaging apparatus includes an image capture device, which includes an optical transmitter, which is configured to emit one or more pulses of infrared radiation toward an area containing a body surface of a living subject, and an optical receiver, which is configured to receive the pulses reflected from the body surface and to generate an output indicative of a modulation of the pulses by tissue below the body surface. A processor is configured to generate, based on the modulation of the pulses, an image of blood vessels located beneath the body surface within the area.

Abstract: Imaging apparatus includes an image sensor, which acquires an image of a scene, and a scanner, which includes an optical transmitter, which emits a sequence of optical pulses toward the scene, and an optical receiver, which receives the optical pulses reflected from the scene and generates an output indicative of respective times of flight of the pulses. Scanning optics are configured to scan the optical pulses over the scene in a scan pattern that covers and is contained within a non-rectangular area within the scene. A processor identifies an object in the image of the scene, defines the non-rectangular area so as to contain the identified object, and processes the output of the optical receiver so as to extract a three-dimensional (3D) map of the object.

Abstract: Optical apparatus includes a scanning line projector, which is configured to scan a line of radiation across a scene. A receiver includes an array of sensing elements, which are configured to output signals in response to the radiation that is incident thereon, and collection optics configured to image the scene onto the array, such that each sensing element receives the radiation reflected from a corresponding point in the scene. A processor is coupled to receive the signals output by the sensing elements, to identify respective times of passage of the scanned line across the points in the scene by comparing a time-dependent waveform of the signals from the corresponding sensing elements to an expected waveform, and to derive depth coordinates of the points in the scene from the respective times of passage.
