Abstract
A light detection and ranging (LIDAR) system is provided that includes an optical source to generate and transmit an optical beam, an optical fiber to guide the optical beam to a fiber tip from which the optical beam is emitted, and a first scanning mirror rotatable along at least one axis to steer the optical beam to scan a scene, and collect light incident upon objects in the scene. The system further includes a first lens, disposed between the optical fiber and the first scanning mirror, to focus the optical beam emitted from the optical fiber to converge at a location near a center of rotation of the first scanning mirror, the first scanning mirror to reflect the optical beam towards an optic, the optic, disposed between the first scanning mirror and the scene, to collimate or focus the optical beam reflected from the first scanning mirror, and a signal processor to determine a range of one or more of the objects from a return signal reflected from the one or more of the objects.
