An optical identification system for identifying a vehicle. The system comprises a laser source for generating a transmitted beam and a reflector in optical communication therewith. The reflector is operative to reflect the transmitted beam to thereby generate a reflected beam. The system further includes a shutter in optical communication with the reflected beam and operative to modulate the polarization of the reflected beam with identification information thereby generating a modulated reflected beam. The optical identification system of the present invention further includes a detector in optical communication with the modulated reflected beam. The detector is operative to pass the modulated reflected beam and decode the identification information modulated thereon.

1. An optical identification system, comprising:a handheld sighting unit; a laser source disposed on the sighting unit for transmitting an unmodulated beam toward a vehicle; a reflector disposable upon a vehicle the reflector being operative to reflect the unmodulated beam to thereby generate a reflected beam; a shutter disposed on the reflector so that the reflected beam must pass through the shutter, the shutter being operative to modulate the polarization of the reflected beam with identification information to thereby generate a modulated reflected beam; and a detector disposed on the sighting unit, the detector being operative to pass the modulated reflected beam and decode the identification information modulated on the modulated reflected beam which passes through.
