Abstract
Systems and methods in a vehicle involve transmitting light with an initial polarization from a lidar system, and controlling an external compensator, external to the lidar system, or an internal compensator within the lidar system to change the initial polarization of the light to a new polarization of the light. The method also includes receiving reflected light resulting from reflection of the light from one or more objects, and obtaining information about the one or more objects based on the reflected light.
