摘要： A motorized optical scanner device (700) of a Light Detection and Ranging (LiDAR) scanning system used in a motor vehicle is disclosed. The motorized optical scanner device (700) comprises a glass-based optical reflector (702) including a plurality of reflective surfaces (704A-E) and a flange (902). The rotatable optical reflector device further comprises an adjustment ring (908) and a metal-based motor rotor body (904) at least partially disposed in an inner opening (920) of the glass-based optical reflector (702). The flange (902) extends from an inner sidewall (912) of the glass-based optical reflector (702) towards the metal-based motor rotor body (904). The flange (902) includes a first mounting surface (922) that is in contact with the adjustment ring (908). The motorized optical scanner device (700) further comprises a plurality of fastening mechanisms (804). The plurality of fastening mechanisms (804) facilitates applying adjustment forces to the adjustment ring (908) to reduce wobble associated with rotation of the glass-based optical reflector (702). When center of a polygon mirror is not perfectly in-line with its center of rotation, tilt angles of polygon facets may change in the process of angular rotation, and the polygon mirror may wobble. During the wobble adjustment process, at least two fastening mechanisms (804), e.g., adjustment screws, may be installed into at least two selected threaded holes (930) in motor assembly (910) to apply adjustment forces, e.g., pushing forces, to the adjustment ring (908) to reduce wobble.

摘要： Various embodiments of a laser scanner apparatus (10) and a method (1400) of operating a laser scanner apparatus (10), as disclosed herein, include the use of a variably blocked aperture (46) or a controlled defocusing in relation to receiving backscattered light (18). One or more embodiments combine both variable blocking and defocusing and may use a lens design that complements the blocking and defocusing. Among the various advantages offered by one or more embodiments disclosed herein is a laser scanner apparatus (10) that exhibits a flatter response curve to backscattered light (18) over a defined range of distances. That is, among other advantages of the configurations and operating methods disclosed herein, a laser scanner apparatus (10) experiences less variation in the optical power delivered to its photodetector (54) arrangement, in relation to detecting an object at different distances within a defined range.

摘要： 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. The emitters respectively emit 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 a plurality of refracted laser beams exiting the prism disk reflect off of the second optic.

摘要： This disclosure describes an example architecture for providing a delay line for optical techniques. The delay line architecture includes a focusing element that has a focal axis disposed parallel to its length. The line of symmetry provided by the focal axis obviates path-length-dependent aberrations caused by the off-axis beam translations. The systems described herein also provide varying geometries of movable mirrors, including a galvanometer mirror and a rotating polygonal mirror. The systems and methods described herein also provide techniques for generating and detecting coherent Raman spectra using a picosecond probe pulse.

摘要： A LIDAR apparatus can include a polygon deflector that includes a plurality of facets. The LIDAR apparatus can include a motor rotatably coupled to the polygon deflector. The motor is configured to rotate the polygon deflector about a first axis orthogonal to a first plane. The LIDAR apparatus can include an optic positioned within an interior of the polygon deflector. The optic collimates a first beam to be incident on a particular facet of the plurality of facets. The particular facet of the plurality of facets refracts the first beam in the first plane between a first angle and a second angle as the polygon deflector rotates about the first axis to output a second beam. For use in an autonomous vehicle.
