US Patent:

6493123, Dec 10, 2002

Filed:

Oct 27, 1999

Appl. No.:

09/427830

Inventors:

Dennis Neal Mansell - Albuquerque NM
Peter Samuel Durkin - Albuquerque NM
Gregory Newton Whitfield - Albuquerque NM
David Wayne Morley - Santa Fe NM

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

H04B 1000

US Classification:

359169, 359170, 342 45

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.
