Abstract
A Lidar system may comprise a rotor and a stator. The rotor is configured to rotate with respect to the stator. The rotor comprises at least one supporting body and a plurality of light sources disposed on the at least one supporting body, the plurality of light sources configured to emit a plurality of first light beams. The plurality of light beams are non-uniformly distributed along a vertical direction in a vertical field of view of the Lidar system.
