Abstract
A lidar system includes a light source configured to emit a beam of light including a sequence of pulses, a scanner configured to scan, using the sequence of pulses, a field of regard of the lidar system along a horizontal dimension and a vertical dimension in accordance with a first scan pattern; a receiver configured to detect light from at least some of the pulses scattered by one or more remote targets to generate an array of pixels, based on the sequence of pulses of the beam of light. The lidar system is further configured to modify the first scan pattern in view of a result of processing the generated array of pixels to generate a second scan pattern, and scan the field of regard using the sequence of pulses along the horizontal dimension and the vertical dimension in accordance with the second scan pattern.
