Abstract: Sensing apparatus includes a radiation source, which emits pulses of optical radiation toward multiple points in a target scene. A receiver receives the optical radiation that is reflected from the target scene and outputs signals that are indicative of respective times of flight of the pulses to and from the points in the target scene. Processing and control circuitry selects a first pulse repetition interval (PRI) and a second PRI, greater than the first PRI, from a permitted range of PRIs, drives the radiation source to emit a first sequence of the pulses at the first PRI and a second sequence of the pulses at a second PRI, and processes the signals output in response to both the first and second sequences of the pulses in order to compute respective depth coordinates of the points in the target scene.

Abstract: Apparatus for optical sensing includes first matrix of optical sensing elements, arranged on a semiconductor substrate in rows and columns. A second matrix of storage nodes is arranged on the substrate such that respective first and second storage nodes in the second matrix are disposed in proximity to each of the sensing elements within the first matrix. Switching circuitry couples each of the sensing elements to transfer photocharge to the respective first and second storage nodes. Control circuitry controls the switching circuitry in a depth sensing mode such that over a series of detection cycles, each of the sensing elements and a first neighboring sensing element are connected together to the respective first storage node during the first detection interval, and each of the sensing elements and the second neighboring sensing element are connected together to the respective second storage node during the second detection interval.

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: 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: The sensitivity of one or more single-photon avalanche diodes (SPAD) in a SPAD detector is modulated over time. The sensitivity of all of the SPADs may be modulated, or the sensitivity of one section of the SPADs can be modulated differently from another section of the SPADs. Various techniques for modulating the sensitivity are disclosed.

Abstract: Depth sensing apparatus includes a radiation source, which is configured to emit a first plurality of beams of light pulses toward a target scene. An array of a second plurality of sensing elements is configured to output signals indicative of respective times of incidence of photons on the sensing element, wherein the second plurality exceeds the first plurality. Light collection optics are configured to image the target scene onto the array of sensing elements. Processing and control circuitry is coupled to receive the signals from the array and is configured to search over the sensing elements in order to identify, responsively to the signals, respective regions of the array on which the light pulses reflected from the target scene are incident, and to process the signals from the identified regions in order determine respective times of arrival of the light pulses.

Abstract: Apparatus for optical sensing includes an illumination assembly, which directs optical radiation toward a target scene while modulating the optical radiation with a carrier wave having a predetermined carrier frequency. A detection assembly includes an array of sensing elements, which output respective signals in response to the optical radiation that is incident on the sensing elements during each of a plurality of detection intervals, which are synchronized with the carrier frequency at different, respective temporal phase angles, and objective optics, which form an image of the target scene on the array. Processing circuitry processes the signals output by the sensing elements in order to compute depth coordinates of the points in the target scene by combining the signals output by respective groups of more than four of the sensing elements.
