Abstract
A scanning lidar system includes a fixed frame, a first platform, and a first electro-optic assembly. The first electro-optic assembly includes a first laser source and a first photodetector mounted on the first platform. The scanning lidar system further includes a first flexure assembly flexibly coupling the first platform to the fixed frame, and a drive mechanism configured to scan 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. The scanning lidar system further includes a controller coupled to the drive mechanism. The controller is configured to cause the drive mechanism to scan the first platform in a first direction with a first frequency and in a second direction with a second frequency. The second frequency is similar but not identical to the first frequency.
