Abstract: An electro-optical device includes a laser light source, which emits at least one beam of light pulses, a beam steering device, which transmits and scans the at least one beam across a target scene, and an array of sensing elements. Each sensing element outputs a signal indicative of a time of incidence of a single photon on the sensing element. Light collection optics image the target scene scanned by the transmitted beam onto the array. Circuitry is coupled to actuate the sensing elements only in a selected region of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.

Abstract: Scanning apparatus includes a base and a gimbal, including a shaft that fits into rotational bearings in the base and is configured to rotate through 360° about a gimbal axis relative to the base. A mirror assembly, fixed to the gimbal, includes a mirror, which is positioned on the gimbal axis and is configured to rotate about a mirror axis perpendicular to the gimbal axis. A transmitter directs pulses of optical radiation toward the mirror, which directs the optical radiation toward a scene. A receiver, receives, via the mirror, the optical radiation reflected from the scene and outputs signals in response to the received radiation. Control circuitry drives the gimbal to rotate about the gimbal axis and the mirror to rotate about the mirror axis, and processes the signals output by the receiver in order to generate a three-dimensional map of the scanned area.

Abstract: Mapping apparatus includes a transmitter, which is configured to emit at least one beam including a sequence of pulses of light toward a plurality of points in a scene. A receiver is configured to receive the light reflected from the scene and to generate an output indicative of a time of flight of the pulses to and from the points in the scene. A processor is coupled to process the output of the receiver so as to generate a 3D map of the scene, while controlling a power level of the pulses emitted by the transmitter responsively to a level of the output from the receiver in response to one or more previous pulses.

Abstract: Apparatus for mapping includes a radiation source, which is configured to emit a beam of radiation, and a detector and optics, which define a sensing area of the detector. A scanning mirror assembly is configured to receive and scan the emitted beam over a selected angular range within a region of interest while scanning the sensing area over the selected angular range in synchronization with the scanned beam from the radiation source. A processor is configured to process signals output by the detector in order to construct a three-dimensional (3D) map of an object in the region of interest.

Abstract: An electro-optical device includes at least one laser light source and a beam steering device, which transmits and scan the at least one beam across a target scene. One or more sensing elements output a signal indicative of a time of incidence of a single photon on the sensing element from the target scene. Circuitry processes the signal in order to determine respective distances to points in the scene and controls the light source to emit the beam at the low level during a first scan, to identify, based on the first scan, the points in the scene that are located at respective distances from the device that are greater than a predefined threshold distance, and to control the laser light source during a second scan to emit the beam at the high level while the beam steering device directs the beam toward the identified points.

Abstract: Optical apparatus (64) includes a stator assembly (47), which includes a core (78, 90, 91) containing an air gap and one or more coils (80, 92, 94, 116, 120) including conductive wire wound on the core so as to cause the core to form a magnetic circuit through the air gap in response to an electrical current flowing in the conductive wire. A scanning mirror assembly (45, 83, 85, 130) includes a support structure (68), a base (72), which is mounted to rotate about a first axis relative to the support structure, and a mirror (46), which is mounted to rotate about a second axis relative to the base. At least one rotor (76, 132) includes one or more permanent magnets, which are fixed to the scanning mirror assembly and which are positioned in the air gap so as to move in response to the magnetic circuit. A driver (82) is coupled to generate the electrical current in the one or more coils.

Abstract: Imaging apparatus includes an illumination assembly, including a plurality of radiation sources and projection optics, which are configured to project radiation from the radiation sources onto different, respective regions of a scene. An imaging assembly includes an image sensor and objective optics configured to form an optical image of the scene on the image sensor, which includes an array of sensor elements arranged in multiple groups, which are triggered by a rolling shutter to capture the radiation from the scene in successive, respective exposure periods from different, respective areas of the scene so as to form an electronic image of the scene. A controller is coupled to actuate the radiation sources sequentially in a pulsed mode so that the illumination assembly illuminates the different, respective areas of the scene in synchronization with the rolling shutter.
