Abstract: A lidar module includes a laser transceiver assembly configured to transmit and receive at least one laser beam and a lens scanning assembly integrated with the laser transceiver assembly. The lens scanning assembly has a movable lens arranged on an optical path of the laser beam transmitted by the laser transceiver assembly. The movable lens is configured with a way of movement in which the movable lens moves in a plane perpendicular to an optical axis of the movable lens to adjust a deflection direction of the laser beam. The present invention is intended to provide a lidar module, which can resolve a defect of a small detection field of view (FOV) of a lidar and realize modularization and miniaturization of a lens scanning assembly and a lidar.
