System and method for non-contact identification of a passive target
Abstract:
A system and method includes a laser transmitter configured to form a transmitted laser beam and a laser receiver configured to receive a reflected beam based on the transmitted laser beam. An identification (ID)-filter includes a substrate, a retarder filter and a reflector, where the transmitted beam passes through the retarder filter and is reflected back through the retarder filter in an opposite direction, to the laser receiver. A processor connected with a memory executes instructions stored in the memory to determine polarization properties of the reflected beam with respect to the transmitted laser beam to determine an address of the ID-filter.
