Claim 4:
5. An autonomous vehicle control system comprising one or more processors, wherein the one or more processors are configured to:
cause a laser source to output a beam;
cause a transmitter to transmit a transmit signal that is generated based on the beam;
cause a receiver to receive a return signal reflected by an object;
cause one or more optics to generate a first signal and a second signal based on the return signal wherein the first signal and the second signal have different polarizations;
calculate a reflectivity value of the object based on a ratio of a signal-to-noise ratio (SNR) value of the first signal and a SNR value of the second signal;
determine a type of the object based on the reflectivity value of the object; and
operate a vehicle based on the type of the object.
