Abstract
A lidar system includes a light source configured to produce a first and second beams of light, receivers to configured to detect light from the first and second beams of light and scattered by one or more remote targets, and a scanner including a first scan mirror configured to pivot along a first-mirror pivot axis to scan the first beam of light along a first direction, a second scan mirror configured to pivot along a second-mirror pivot axis to scan the second beam of light along the first direction, and a polygon with multiple reflective surfaces configured to rotate about a polygon-mirror rotation axis to scan the first and second beams of light along a second direction.
