  • Modulated-retroreflector based optical identification system
    Patent number: 6493123
    Abstract: 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.
