Claim 9:
10. A system for differentiating a ghost from a real object in sensor data, the system comprising:
a processor; and
a memory containing programming instructions that are configured to cause the processor to:
receive data collected by a light detector unit,
analyze, in the data, characteristics of beams of reflected light received by the light detector unit, wherein:
the beams reflected light correspond to beams of emitted light directed toward an object;
the beams of reflected light exhibit varying intensities; and
the beams of emitted light exhibited varying polarizations,

identify a reflection position that is associated with the reflected light,
use characteristic differences between a polarization pattern of the beams of emitted light and an intensity pattern of the beams of reflected light to assess whether the reflection position is a position of the object or a position of a ghost, and
in response to the polarization pattern of the beams of emitted light substantially corresponding to the intensity pattern of the beams of reflected light, determine that the reflection position is a position of a ghost.
