Abstract

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 facet. 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.
