Patent number: 10955555Abstract: 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.Type: GrantFiled: August 13, 2019Date of Patent: March 23, 2021Assignee: APPLE INC.Inventors: Thierry Oggier, Scott T.
