Abstract
A scanning LiDAR system includes a base frame, an optoelectronic assembly, and a lens assembly. The optoelectronic assembly includes one or more laser sources and one or more photodetectors, and is fixedly attached to the base frame. The lens assembly includes one or more lenses. The one or more lenses have a focal plane. The scanning LiDAR system further includes a first flexure assembly flexibly coupling the lens assembly to the base frame. The first flexure assembly is configured such that the one or more laser sources and the one or more photodetectors are positioned substantially at the focal plane of the one or more lenses. The first flexure assembly is further configured to be flexed so as to scan the lens assembly laterally in a plane substantially perpendicular to an optical axis of the emission lens.
