Filed:

Jun 5, 2002

Appl. No.:

10/163062

Inventors:

Paul G. Coombs - Santa Rosa CA, US
Donald M. Friedrich - Santa Rosa CA, US
Ken D. Cardell - Tucson AZ, US
Curtis R. Hruska - Santa Rosa CA, US

Assignee:

Flex Products, Inc. - Santa Rosa CA

International Classification:

G06K 9/74

US Classification:

356 71

Abstract:

An automated verification system for authenticating an object having an optical security feature includes an optical system, a transport staging apparatus, and an analyzing device. The optical system includes one or more light sources that are capable of generating either narrowband or broadband light beams. The transport staging apparatus cooperates with the light sources and is configured to position the object such that one or more of the light beams strike a portion of the object where the security feature should be located. The analyzing device receives the light beams reflected or transmitted from the object and is adapted to analyze the optical characteristics of the light beams at varying angles and/or wavelengths to verify the authenticity of the object.
