Abstract: A LIDAR system includes a first prism disk rotatable about a first axis at a first rotational speed; a first LIDAR unit having a first plurality of emitters to emit a first plurality of laser beams which pass through the first prism disk to produce a first plurality of refracted laser beams; a second prism disk rotatable about a second axis at a second rotational speed; a second LIDAR unit having a second plurality of emitters to emit a second plurality of laser beams which pass through the second prism disk to produce a second plurality of refracted laser beams; and an optic rotatable about a third axis at a third rotational speed that is faster than at least one of the first rotational speed or the second rotational speed. The optic reflects the first plurality of refracted laser beams and reflects the second plurality of refracted laser beams.

Abstract: A 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 telecentric lens assembly positioned within the cavity and along the transmit path such that the laser beam emitted from each of the plurality of emitters passes through the first telecentric lens assembly. The LIDAR further includes a second telecentric lens assembly positioned within the cavity and along a receive path such that a plurality of reflected laser beams entering the cavity pass through the second telecentric lens assembly. The first telecentric lens assembly and the second telecentric lens assembly each include a field flattening lens and at least one other lens.
