Claim 0:
1. A method of differentiating a ghost from a real object in data collected by a sensor system, the method comprising:
analyzing, by a processor, characteristics of beams of reflected light received by the sensor system, wherein the beams of reflected light correspond to beams of emitted light directed toward an object;
determining, by the processor, characteristic differences between a polarization pattern of the emitted beams of light and an intensity pattern of the beams of reflected light;
identifying, by the processor, a reflection position associated with the reflected light;
assessing, by the processor using the determined characteristic differences between the polarization pattern of the emitted beams of light and the intensity pattern of the beams of reflected light, whether the reflection position is a position of the object or a position of a ghost; and
determining, by the processor, that the reflection position is a position of a ghost in response to the polarization pattern of the emitted beams of light substantially corresponding to the intensity pattern of the beams of reflected light.
