Abstract: A light detection and ranging (LIDAR) sensor system includes a transmitter, one or more scanning optics, an optical module, and a receiver. The transmitter is configured to output a beam having a linear polarization. The optical module is configured to provide the beam to the one or more scanning optics. The one or more scanning optics are configured to output the beam received from the optical module. The receiver is spaced from the transmitter and receiver configured to receive a return beam from reflection of the beam by an object.

Abstract: An autonomous vehicle control system includes one or more processors. The one or more processors are configured to cause a transmitter to transmit a transmit signal from a laser source. The one or more processors are configured to cause a receiver to receive a return signal reflected by an object. The one or more processors are configured to cause one or more optics to generate a first polarized signal of the return signal with a first polarization, and generate a second polarized signal of the return signal with a second polarization. The one or more processors are configured to calculate a value of reflectivity based on a signal-to-noise ratio (SNR) value of the first polarized signal and an SNR value of the second polarized signal. The one or more processors are configured to operate a vehicle based on the value of reflectivity.
