Systems and methods are provided herein for improved short range object detection in LiDAR systems. The associated systems may include a first portion and a second portion configured to rotate relative to one another. The system may also include a first magnet located on the second portion and arranged with a north pole of the first magnet facing a first direction. The system may also include a second magnet located on the second portion and arranged with a south pole of the second magnet facing the first direction. The system may also include a first sensor located on the first portion, wherein the first sensor is further configured to measure a first magnetic field of the first magnet and a second magnetic field of the second magnet as the first portion and second portion rotate relative to one another.
