Claim 0:
1. A light detection and ranging (LiDAR) system for use with a vehicle, 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; and
a moveable mirror positioned to redirect the light energy passing between the light source and the polygon structure, the moveable 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 moveable 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 moveable 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.
