The pixel array sensor arranged to receive photons of light reflected by the target. The processor arranged to determine a time-of-flight for the received photons and to further determine a depth of the target by (i) assigning a histogram that includes a bin number of bins to each pixel, (ii) comparing the histogram of each pixel with an expected shape and (iii) determining the time- of-flight for each pixel based on the comparison of the histogram and the expected shape.

Abstract: A LiDAR system includes a transmitter having a first and second laser emitter generating first and second optical beams and projecting the optical beams along a transmitter optical axis. A receiver includes an array of pixels positioned with respect to the receive optical axis such that light from the first optical beam reflected from an object forms a first image area and light from the second optical beam reflected by the object forms a second image area on the array of pixels such that an overlap region between the first image area and the second image area is formed based on a measurement range and on a relative position of the transmitter optical axis and the receive optical axis. A processor determines what pixels are in the overlap region from electrical signals generated by at least one pixel in the overlap region and generates a return pulse in response.

Abstract: A Light Detection and Ranging (LIDAR) circuit includes a non-transitory memory device comprising a first memory and a second memory, and at least one control circuit. The at least one control circuit is configured to execute first memory storage operations to store data indicated by detection signals received from one or more photodetector elements in the first memory during a time between pulses of an emitter signal output from a LIDAR emitter element, and execute second memory storage operations to include previous data indicated by previous detection signals received from the one or more photodetector elements, which was stored in the first memory, in respective memory bins of the second memory. The first and second memory storage operations are executed at least partially concurrently. Related devices and methods of operation are also discussed.

Abstract: Apparatus and methods for determining the distance to an object by detecting a reflected light beam. A light emitter emits a light beam. An optical fiber is mounted to direct the light beam as an output light beam of the optical fiber. An actuator is coupled proximate a distal end of the optical fiber, for moving the distal end of the optical fiber in a desired pattern. Collimation optics are mounted to intercept the output light beam of the optical fiber and collimate the output light beam of the optical fiber. A photodetector is mounted to receive a reflected light beam after reflecting off an object in an external environment. A control system determines a distance to the object based on an elapsed time between emission of the light beam and a detection of the reflected light beam by the photodetector.
