Abstract

A headlamp module of a vehicle includes a housing including a window, an illumination submodule disposed inside the housing and configured to provide illumination light to be transmitted through the window toward a scene in front of the vehicle, and a first LiDAR sensor disposed inside the housing and laterally displaced from the illumination submodule. The first LiDAR sensor includes one or more laser sources configured to emit laser beams to be transmitted through the window toward the scene, the laser beams being reflected off of one or more objects in the scene, thereby generating return laser beams to be transmitted through the window toward the first LiDAR sensor and one or more detectors configured to receive and detect the return laser beams.
