Abstract
A lidar system may have a light source configured to emit pulses of light along a field of view of the light source and a scanner to scan the light source field of view in a scanning direction across a plurality of pixels located downrange from the lidar system. The scanner can direct a pulse of light, which is emitted by the light source along the light source field of view, toward a pixel and can scan a field of view of a first detector. The first detector field of view can be scanned in the scanning direction across the plurality of pixels and the scanning speed of the first detector field of view can be approximately equal to the scanning speed of the light source field of view. The first detector can detect a portion of the pulse of light scattered by a target located at least partially within the pixel.
