Abstract
A light detection and ranging (LIDAR) system is provided that includes an optical a scanning mirror to steer a laser beam emitted from the tip of an optical fiber to scan a scene, and collect light incident upon any objects in the scene that is returned to the fiber tip. The LIDAR system further includes a re-imaging lens located between the optical fiber and scanning mirror, and an optic located between the scanning mirror and the scene. The re-imaging lens focuses the laser beam emitted from the optical fiber on or close to the first scanning mirror's center of rotation and thereby re-image the fiber tip at or close to the center of rotation, from which the laser beam is reflected as a divergent laser beam. And the optic is configured to collimate or focus the divergent laser beam from the first scanning mirror that is launched toward the scene.
