Claim 22:
23. A light detection and ranging (LiDAR) system comprising:
a light source configured to transmit light energy via a plurality of light beams;
a polygon structure that controls a horizontal angle of a field of view of the LiDAR system, wherein the polygon structure has a trapezoidal cross section, further wherein the polygon structure has a first facet and a second facet, wherein the first facet is non-parallel to the second facet; and
a multi-plane mirror positioned to redirect the light energy passing between the light source and the polygon structure, the multi-plane mirror configured to control a vertical field of view of the LiDAR system; and
a region of interest controller configured to:
adjust a movement speed of the moveable mirror such that the LiDAR system has a different vertical angle scan resolution within a region of interest from an area outside of the region of interest, and
adjust light pulse intervals of the light energy such that the LiDAR system has a different horizontal angle scan resolution within the region of interest from the area outside of the region of interest,
wherein outside of the region of interest, the multi-plane mirror is configured such that a plurality of immediately adjacent horizontal scan lines are from different light beams of the plurality of light beams, and
wherein within the region of interest, the multi-plane mirror is configured such that at least two immediately adjacent horizontal scan lines are from a same light beam of the plurality of the light beams.
