    摘要: An automated verification system for authenticating an object having an interference security device or feature includes an electromagnetic radiation source capable of generating one or more electromagnetic radiation beams, a transport staging apparatus adapted to position an object in the path of the one or more electromagnetic radiation beams, and an analyzing system adapted to receive the one or more electromagnetic radiation beams from the object and, based upon the characteristics of the received electromagnetic radiation, determine if the object is authentic. The analyzing system is configured to analyze the characteristics of electromagnetic radiation beams at varying angles and/or wavelengths from the object to verify the authenticity of the object. One exemplary method utilizes spectra representative of the electromagnetic radiation received from the object at one or more angles. The slope direction of the spectra is compared against reference data that represents spectra for an authentic object.
