Claim 12:
13. An autonomous vehicle control system for an autonomous vehicle, the autonomous vehicle control system comprising:
a light detection and ranging (LIDAR) device including one or more LIDAR pixels, wherein at least one of the one or more LIDAR pixels includes:
a dual-polarization optical antenna configured to: (i) emit a transmit beam with a first polarization orientation, and (ii) detect a return beam having a second polarization orientation;
a second optical antenna offset from the dual-polarization optical antenna by a particular distance, wherein the second optical antenna is configured to detect the return beam having the second polarization orientation; and
one or more receivers configured to generate one or more signals in response to detecting the second polarization orientation of the return beam; and

one or more processors configured to control the autonomous vehicle in response to the one or more signals.
