1. A light detection and ranging (LiDAR) system for use with a vehicle, comprising:
a transmitter comprising:
a plurality of semiconductor based light emitters configured to generate light energy, and
a lens group,
wherein the lens group is configured to collimate the generated light energy to obtain collimated light energy and to direct the collimated light energy along a plurality of different angles, the combination of the plurality of different angles forming at least a part of a vertical angle range of a field of view of the LiDAR system;
a receiver configured to receive light energy reflected from an object within the field of view of the LiDAR system;
a polygon structure that defines a horizontal angle range of the field of view of the LiDAR system; and
one or more mirrors configured to redirect light energy passing between the transmitter and the polygon structure, and to redirect light energy passing between the polygon structure and the receiver, wherein a position of one of the one or more mirrors 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.
