1. A LIDAR sensor for an autonomous vehicle (AV), comprising:

  • a set of mirrors;

    a set of lasers outputting laser beams via the set of mirrors; and

    one or more mirror actuators to adjust the set of mirrors, in response to AV feedback from the AV, to reconfigure a beam pattern of the outputted lasers;

    wherein the AV feedback indicates a speed of the AV, wherein the one or more mirror actuators reconfigure the beam pattern by modifying a vertical angular spacing of the outputted laser beams, and wherein the one or more mirror actuators dynamically increase the vertical angular spacing as the AV decreases speed, and dynamically decrease the vertical angular spacing as the AV increases speed.
