Abstract

A light detection and ranging (LiDAR) system includes light emitters that emit beams of light of substantially equal intensities. The light emitters form a beam polarization pattern with beams having varying polarizations. The LiDAR system also will include a receiver to receive light reflected from the object. An analyzer will determine characteristic differences between the beam polarization pattern of the beams emitted toward the object and an intensity pattern of the light reflected from the object, determine a reflection position that is associated with the light reflected from the object, and use the determined characteristic differences to determine whether the reflection position is a position of the object or a position of a ghost.
