Abstract
A LIDAR system includes a LIDAR unit. The LIDAR unit includes a housing defining a cavity. The LIDAR unit further include a plurality of emitters disposed on a circuit board within the cavity. Each of the emitters emits a laser beam along a transmit path. The LIDAR system further includes a first optic rotatable about a first axis at a first rotational speed and a second optic rotatable about a second axis at a second rotational speed that is faster than the first rotational speed. The first optic is positioned relative to the LIDAR unit such that a plurality of laser beams exiting the LIDAR unit pass through the first optic. The second optic is positioned relative to the first optic such that each of a plurality of refracted laser beams exiting the prism disk reflect off of the second optic.
