    Abstract: An electro-optical device (20) includes a laser (28), which is configured to emit toward a scene (38) pulses (36) of optical radiation. An array (34) of detectors (79) are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. A controller (26) is coupled to drive the laser to emit a sequence of pulses of the optical radiation toward each of a plurality of points in the scene and to find respective times of flight for the points responsively to the output signals, while controlling a power of the pulses emitted by the laser by counting a number of the detectors outputting the signals in response to each pulse, and reducing the power of a subsequent pulse in the sequence when the number is greater than a predefined threshold.

    Abstract: Optical systems that may, for example, be used in remote sensing systems, for example in systems that implement combining laser pulse transmission in LiDAR and that include dual transmit and receive systems. A dual receiver system may include a receiver including an optical system with a relatively small aperture and wide field of view for capturing reflected light from short-range (e.g., 20 meters) objects. The optical systems may refract the reflected light to photodetectors (e.g., single photo-avalanche detectors (SPADs)) that capture the light. Light captured at the photodetectors may, for example, be used to determine range information for objects or surfaces in the environment.

    Abstract: An electro-optical device (18) includes a laser light source (20), which emits at least one beam of light pulses, a beam steering device (24), which transmits and scans the at least one beam across a target scene (22), and an array (28) of sensing elements (44). Each sensing element outputs a signal indicative of a time of incidence of a single photon on the sensing element. Light collection optics (27) image the target scene scanned by the transmitted beam onto the array. Circuitry (50) is coupled to actuate the sensing elements only in a selected region (70) of the array and to sweep the selected region over the array in synchronization with scanning of the at least one beam.
