Publication number: 20140247499Abstract: A security element for integration into documents for authentication thereof. The security element comprises a substrate. A reflective optical structure and a reference pattern are disposed on the same side of the substrate. The reflective optical structure is made up of an array of Fresnel lenses. The reference pattern appears in the foreground when observed by an observer. A virtual image of the observer appears in the background behind the foreground pattern.Type: ApplicationFiled: March 3, 2014Publication date: September 4, 2014Applicant: ARJOWIGGINS SECURITYInventors: Pierre Doublet, Michel Camus

Publication number: 20140175786Abstract: A security element for integration into a document. The security element has a transparent substrate. An array of lenses is disposed on the first side of the substrate. A field of elementary patterns observable through the array of lenses is disposed on the second side of the substrate. A transparent lacquer partially covers the array of lenses. The lacquer takes the form of at least one macroscopic pattern, which locally cancels out the effect of the lenses, thereby allowing an observation of the field of underlying elementary patterns tin halftone. The macroscopic patterns are not spatially coordinated with the field of elementary patterns.Type: ApplicationFiled: February 28, 2014Publication date: June 26, 2014Applicant: ARJOWIGGINS SECURITYInventors: Pierre Doublet, Michel Camus

Publication number: 20140151996Abstract: A security element adapted for integration into a security document. The security element having a substrate with a first face and a second face. An optical structure is disposed on the first face, and at least two patterns are inscribed on the second face. The two patterns are at least partially identical. The first pattern is observable at a first position on the second face through the optical structure along a first viewing angle. The second pattern is observable at a second position on the second face through the optical structure along a second viewing angle. Authenticity of the document may be verified by comparing the observed patterns.Type: ApplicationFiled: June 24, 2013Publication date: June 5, 2014Inventor: Michel Camus
