1. A light detection and ranging (LIDAR) sensor system, comprising:
a first polygon scanner comprising a plurality of first facets arranged around an axis of rotation;
a second polygon scanner comprising a plurality of second facets arranged around the axis of rotation, each second facet of the plurality of second facets outward from the first polygon scanner relative to the axis of rotation;
an optic configured to output a first beam to the first polygon scanner, the first polygon scanner is configured to refract the first beam to output a second beam to the second polygon scanner, and the second polygon scanner is configured to refract the second beam to output a third beam; and
at least one motor configured to rotate the first polygon scanner about the axis of rotation and to rotate the second polygon scanner about the axis of rotation.
