Abstract:
1. A system for verifying the authenticity of an object comprising: one or more light sources for providing one or more beams of light; an array of optical detectors configured to receive the one or more beams of light directed along a first optical path from the object where a color shifting optical interference security feature should be located, the array of optical detectors adapted to measure the light beam over a range of spectral wavelengths to generate a spectral curve corresponding to the reflectance or transmittance spectra of the security feature; and (c) a data analyzing device operatively connected to the optical detector and adapted to analyze the spectral curve generated by the optical detector to verify the authenticity of the object, wherein the one or more light sources is located adjacent to the array of optical detectors, and wherein the data analyzing device includes means for comparing detected spectral related information as a function of angle of reflection with stored color related information.
