Abstract
A LiDAR system includes a fixed frame, a first platform, an electro-optic assembly including one or more laser sources and one or more detectors mounted on the first platform; a flexure assembly flexibly coupling the first platform to the fixed frame; a drive mechanism configured to translate the first platform with respect to the fixed frame in two dimensions in a plane substantially perpendicular to an optical axis of the LiDAR system; and a controller configured to cause the drive mechanism to translate the first platform in a first direction with a first frequency and in a second direction orthogonal to the first direction with a second frequency that is different from the first frequency, acquire a point cloud, and output the point cloud at a frame rate that is an integer times a difference between the second frequency and the first frequency, the integer being greater than one.
