Abstract
A light detection and ranging (LIDAR) sensor system includes a dual-polarization optical antenna, a single-polarization optical antenna, a first receiver, and a second receiver. The dual-polarization optical antenna is configured to (i) emit a transmit beam with a first polarization orientation and (ii) and detect a return beam having a second polarization orientation. The single-polarization optical antenna is configured to detect the return beam having the second polarization orientation.

1-20. (canceled)
A light detection and ranging (LIDAR) system for a vehicle, the LIDAR system comprising:
- one or more LIDAR pixels, wherein at least one of the one or more LIDAR pixels includes:
- a first optical antenna configured to emit a transmit beam having a first polarization orientation;
- a second optical antenna that is offset from the first optical antenna by a particular distance, wherein the second optical antenna is configured to detect a return beam having a 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.
An autonomous vehicle (AV) control system comprising:
- a light detection and ranging (LIDAR) system comprising:
- one or more LIDAR pixels, wherein at least one of the one or more LIDAR pixels includes:
