Abstract: A LIDAR system includes a plurality of LIDAR units. Each of the LIDAR units includes a housing defining a cavity. Each of the LIDAR units further includes a plurality of emitters disposed within the cavity. Each of the plurality of emitters is configured to emit a laser beam. The LIDAR system includes a rotating mirror and a retarder. The retarder is configurable in at least a first mode and a second mode to control a polarization state of a plurality of laser beams emitted from each of the plurality of LIDAR units. The LIDAR system includes a polarizing beam splitter positioned relative to the retarder such that the polarizing beam splitter receives a plurality of laser beams exiting the retarder. The polarizing beam is configured to transmit or reflect the plurality of laser beams exiting the retarder based on the polarization state of the laser beams exiting the retarder.

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.

Abstract: A LIDAR assembly is provided. The LIDAR assembly includes a LIDAR unit. The LIDAR unit includes a housing defining a cavity. The LIDAR unit further includes a plurality of emitters disposed within the cavity. Each of the plurality of emitters is configured to emit a laser beam. The LIDAR assembly further includes a switchable mirror. The switchable mirror is positioned relative to the LIDAR unit such that the switchable mirror receives a plurality of laser beams exiting the housing of the LIDAR unit. The switchable mirror is configurable in at least a reflective state to direct the plurality of laser beams along a first path and a transmissive state to direct the plurality of laser beams along a second path that is different than the first path to widen a field of view of the LIDAR unit along a first axis.

Abstract: A LIDAR assembly defining a horizontal axis and a vertical axis is provided. The LIDAR assembly includes a LIDAR unit. The LIDAR unit includes a housing defining a cavity. The LIDAR unit further includes a first plurality of emitters disposed within the cavity and a second plurality of emitters disposed within the cavity. Each of the first plurality of emitters is configured to emit a first laser beam at a first wavelength. Conversely, each of the second plurality of emitters is configured to emit a second laser beam at a second wavelength that is different than the first wavelength. The LIDAR assembly includes an optic positioned outside of the housing. The optic is configured to optically act on the first laser beam and the second laser beam in a different manner to widen a field of view of the LIDAR unit along the vertical axis.
