POLARIZATION SENSITIVE LIDAR SYSTEM

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 havingvarying 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. 激光雷达(LiDAR)系统包括发射光发射器，所发射光束的强度大致相同。光发射器通过发射偏振不同的光束形成光束偏振图样。所述激光雷达系统还包括一个接收器，以接收物体反射光。分析器识别发射至物体光束的光束偏振图样与物体反射光的强度图样之间的特征差异，以及确定与所述物体反射光相关的反射位置。然后运用所识别的特征差异判断所述反射位置是物体位置还是虚影位置。
