Claim 26:
27. A lidar system comprising:
one or more light sources configured to generate a first beam of light and a second beam of light;
a scanner configured to scan the first and second beams of light across a field of regard of the lidar system, the scanner comprising:
a rotatable polygon mirror comprising a plurality of reflective surfaces angularly offset from one another along a periphery of the polygon mirror, the reflective surfaces configured to reflect the first and second beams of light to produce a series of scan lines as the polygon mirror rotates; and
a pivotable scan mirror configured to (i) reflect the first and second beams of light and (ii) pivot to distribute the scan lines across the field of regard; and

a receiver configured to detect the first beam of light and the second beam of light scattered by one or more remote targets, wherein the receiver comprises:
a first detector configured to detect the first beam of scattered light, and
a second detector configured to detect the second beam of scattered light, wherein:

the scanner is configured to scan the first beam of light so that a field of view (FOV) associated with the first beam of light is scanned synchronously with a FOV associated with the first detector, wherein the FOV of the first beam of light is scanned along a same scan direction and at a same scan speed as the FOV of the first detector, and the FOV of the first beam of light and the FOV of the first detector maintain a same relative position to one another so that the FOV of the first detector is offset from the FOV of the first beam of light by a fixed amount in a direction opposite the scan direction.
