    摘要: 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.

    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.

    摘要: Interference pigment flakes and foils are provided which have luminescent and color-shifting properties. The pigment flakes can have a symmetrical coating structure on opposing sides of a core layer, can have an asymmetrical coating structure with all of the layers on one side of the core layer, or can be formed with encapsulating coatings around the core layer. The coating structure of the flakes and foils includes a core layer, a dielectric layer overlying the core layer, and an absorber layer overlying the dielectric layer. A luminescent material is incorporated into the flakes or foils as a separate layer or as at least part of one or more of the other layers. The pigment flakes and foils exhibit a discrete color shift so as to have a first color at a first angle of incident light or viewing and a second color different from the first color at a second angle of incident light or viewing. The pigment flakes can be interspersed into liquid media such as paints or inks to produce colorant materials for subsequent application to objects or papers. The foils can be laminated to various objects or can be formed on a carrier substrate.
