1. A light detection and ranging (LiDAR) system for use with a vehicle, the LiDAR system comprising:
a transceiver configured to transmit and receive light;
a polygon structure that defines a lateral angle of a field of view of the LiDAR system, the polygon structure having a symmetric axis, wherein the polygon structure comprises a reflective facet that is non-parallel to the symmetric axis; and
a moveable mirror positioned to redirect light passing between the transceiver and the polygon structure, the moveable mirror configured to adjust angles of light being directed between the transceiver and the polygon structure, wherein the moveable mirror defines a vertical angle of the field of view of the LiDAR system, and wherein a position of the moveable mirror is translatable in a manner that results in an increase of scan resolution of at least a part of the field of view of the LiDAR system.
