Circular polarization LiDAR: a robust pathway to resist sunlight contamination

We propose an effective anti-interference LiDAR concept, called circular polarization LiDAR. It can effectively and robustly resist sunlight interference, which has been a longstanding challenge for NASA and the broader research community. Experimental results demonstrate the great potential of circular polarization LiDAR for resisting the sunlight interference. Its strong anti-interference ability is expected to open new directions in LiDAR technology, particularly for ocean detection applications.
