Abstract: A LiDAR and a movable device are disclosed. The LiDAR includes a first optical transceiving module, a first reflecting module, and a galvanometer module. The galvanometer module includes a galvanometer and a first driving mechanism. The galvanometer is configured to receive a detection light emitted from the first reflecting mirror of the first reflecting module, and scan a target object. The first driving mechanism is connected to the galvanometer, and the first driving mechanism is configured to drive the galvanometer to move between a first preset position and a second preset position.
