Patent number: 10890485Abstract: An imaging system (200) for generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positioned so that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the electromagnetic radiation is dispersed and imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed electromagnetic radiation and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums.Type: GrantFiled: June 26, 2017Date of Patent: January 12, 2021Assignee: SICPA HOLDING SAInventors: Jean-Luc Dorier, Xavier-Cédric Raemy, Todor Dinoev, Edmund Halasz

Patent number: 10699506Abstract: An imaging system (200) for imaging and generating a measure of authenticity of an object (10) comprises a dispersive imaging arrangement (30) and an image sensor arrangement (60). They are positioned so that, when electromagnetic radiation (20) from the object (10) illuminates the dispersive imaging arrangement (30), the radiation splits out in different directions into at least a non-dispersed part (40) and a dispersed part (50), and those are imaged by the image sensor arrangement (60). The imaging system (200) is configured to then generate a measure of authenticity of the object (10) depending at least on a relation between the imaged dispersed part, the imaged non-dispersed part, and reference spectral information. The invention also relates to imaging methods, computer programs, computer program products, and storage mediums.Type: GrantFiled: June 26, 2017Date of Patent: June 30, 2020Assignee: SICPA HOLDINGS SAInventors: Jean-Luc Dorier, Xavier-Cédric Raemy, Todor Dinoev, Edmund Halasz

Patent number: 9946927Abstract: The present invention describes a method for marking an object (18), the object (18) having a surface of a conductive material. The method comprises a step of applying an electric spark to the surface such that the material is at least one of partially melted and partially ablated by the electric spark, thereby forming a pattern on the object (18). Further, the present application relates to a marking system (10) for marking an object (18) using a spark generator (12) having a counter electrode (14) and a connector (16) for electrically connecting the spark generator (12) to the surface of the object (18) to be marked. Further, the present application relates to an authenticating system for authenticating or identifying an object (18) marked by the above described method for marking the object (18).Type: GrantFiled: October 1, 2014Date of Patent: April 17, 2018Assignee: SICPA Holding SAInventors: Edmund Halasz, Jean-Luc Dorier
