Abstract:

An optically based position location system, comprises multiple reflectors positioned at known locations in an environment a vehicle for traveling along a path in the environment a first sensor for generating and detecting a collimated and polarized first light signal reflected from one of the reflectors, and for generating a first output signal in response to detecting the first light signal a second sensor for generating and detecting a collimated and polarized second light signal reflected from the reflector reflecting the first light signal, and for generating a second output signal in response to detecting the second light signal and a data processor which uses the first and second output signals for determining the distance between a reference coordinate-on the vehicle and the reflector.
