Abstract

Disclosed are devices and methods for scanning sensing systems having an array of light sensing pixels, such as pixels that use single-photon avalanche diodes. Light pulses are emitted into a field of view (FOV) at starts of a sequence of time intervals, and a weighted tabulation of the times-of-flight of the reflected light pulses within each time interval is used to detect an object in the FOV and determine its distance. Each weight is based on the time-of-flight between the emitted pulse and the received reflected light pulse and on the number of the emitted light pulse in the sequence of emitted light pulses. For near objects the weights emphasize times-of-flight from peripheral time intervals of the sequence; for far objects the weights emphasize central time intervals of the sequence.
