1. A LiDAR sensor comprising a plurality of vertical cavity surface emitting laser (VCSEL) arrays each including a plurality of VCSELs, said sensor further including a separate lens positioned proximate each VCSEL array that receives and focuses a laser beam from each VCSEL in the particular array, said sensor further comprising a detector assembly for detecting reflected beams reflected from objects that receive the laser beams, where the sensor is configured to increase laser beam on-time for the VCSELs in a particular array in response to detection of said objects.
