摘要： A LIDAR system includes a first polygon scanner, a second polygon scanner, and an optic. The first polygon scanner includes a plurality of first facets around an axis of rotation. The second polygon scanner includes plurality of second facets that are outward from the plurality of first facets relative to the axis of rotation. The optic is inward from the first polygon scanner relative to the axis of rotation. The optic is 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. The second polygon scanner is configured to refract the second beam to output a third beam.

摘要： A LIDAR system includes a laser source, a first scanner, and a second scanner. The first scanner receives a first beam from the laser source and applies a first angle modulation to the first beam to output a second beam at a first angle. The second scanner receives the second beam and applies a second angle modulation to the second beam to output a third beam at a second angle.
