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: A camera includes a pulse transmitter for transmitting at a transmit time through an aperture and along an optical path to a target a coherent electromagnetic ranging pulse at a first wavelength range outside the visible spectrum. In some embodiments, the camera includes a reflected pulse detector for receiving a reflected electromagnetic pulse reflected by the target back along the optical path and through the aperture at a detect time subsequent to the transmit time. In some embodiments, the camera includes a shutter positioned for shielding the pulse detector from at least transmit time to an intermediate time between the transmit time and the detect time. In some embodiments, the shutter includes a layer of semiconductor material placed in the optical path at a point between the target and the detector.
