    摘要: 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.

    摘要: The invention relates to a method of authenticating a magnetically induced mark applied on a substrate including magnetically oriented partially reflective platelet-shaped magnetic or magnetizable pigment particles, with a portable device equipped with a light source operable to deliver visible light, an imager, a processor and a memory, the method comprising calculating, with the processor, a corresponding average intensity I of the light reflected by the partially reflective platelet-shaped magnetic or magnetizable pigment particles and collected by the imager at corresponding viewing angle θ, storing the calculated average intensities of the reflected light and corresponding viewing angles to obtain a reflected light intensity curve I(θ), comparing the stored reflected light intensity curve I(θ) with a stored reference reflected light intensity curve Iref(θ) for said magnetically induced mark, and determining whether the magnetically induced mark is genuine based on a result of the comparison.

    摘要: 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).
