Abstract
Die Erfindung betrifft eine Vorrichtung zur Prüfung von Wertgegenständen, insbesondere Banknoten, und/oder Merkmalen für Wertgegenstände, die eine richtungsabhängige optische Charakteristik aufweisen, die zur Prüfung eine optische Abbildungseinrichtung verwendet, die einen Bildpunkt zweidimensional abbildet, insbesondere in einen Ring, wobei die zweidimensionale Abbildung eine azimutale Intensitätsverteilung aufweist, die durch die Abstrahlcharakteristik des Bildpunkts bestimmt ist.The invention relates to a device for testing valuables, in particular banknotes, and / or features for objects of value, which have a directional optical characteristic which uses an optical imaging device, which images a pixel two-dimensionally, in particular into a ring, wherein the two-dimensional image has an azimuthal intensity distribution determined by the radiation characteristic of the pixel.
Description
Die Erfindung betrifft eine Vorrichtung zur Prüfung von Wertgegenständen, insbesondere Banknoten, und/oder Merkmalen für Wertgegenstände, die eine azimutal richtungsabhängige optische Charakteristik aufweisen. Sie ist aber ganz allgemein zur Prüfung von Oberflächen mit einer solchen Charakteristik verwendbar.The The invention relates to a device for testing valuables, in particular banknotes, and / or features for Valuables, the one azimuthal directional have optical characteristics. But she is in general to exam of surfaces usable with such a characteristic.
Es sind Merkmale für Wertgegenstände, z. B. Banknoten, bekannt, die eine richtungsabhängige optische Charakteristik aufweisen. Derartige Merkmale sind beispielsweise mittels Stahldruck erzeugte Druckbereiche, die reliefartige Strukturen aufweisen. Ein weiteres Beispiel stellen Hologramme oder Kinegramme dar, die auf die Wertgegenstände aufgebracht werden und z. B. Gitterstrukturen aufweisen. Durch die besonderen Strukturen dieser Merkmale ergeben sich richtungsabhängige optische Eigenschaften, d. h. bei einer Betrachtung der Wertgegenstände bzw. deren Merkmale unter einem zur Oberflächennormalen schrägen Winkel kann deren von der Drehung um die Normale abhängige optische Charakteristik wahrgenommen werden.It are features for Valuables, z. B. banknotes, known that a directional optical characteristic exhibit. Such features are for example by means of steel printing generated pressure areas that have relief-like structures. One Another example is holograms or kinegrams, which occur the valuables be applied and z. B. have lattice structures. By the special structures of these features result direction-dependent optical Properties, d. H. in a consideration of the valuables or their characteristics under an angle normal to the surface normal can their dependent on the rotation about the normal optical characteristic be perceived.
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung zur Prüfung von Wertgegenständen, insbesondere Banknoten, und/oder Merkmalen für Wertgegenstände, die eine azimutal richtungsabhängige optische Charakteristik aufweisen, anzugeben, welche es erlaubt, die besondere optische Charakteristik derartiger Merkmale zu erfassen, um diese nachweisen zu können.task It is the object of the present invention to provide a device for testing Valuables, in particular Banknotes, and / or features for valuables, the an azimuthal directional have optical characteristics to indicate which allows to capture the particular optical characteristics of such features, to prove this.
Diese Aufgabe wird durch eine Vorrichtung mit den in Anspruch 1 angegebenen Merkmalen gelöst.These The object is achieved by a device with the specified in claim 1 Characteristics solved.
Die Erfindung betrifft eine Vorrichtung zur Prüfung von Wertgegenständen, insbesondere Banknoten, und/oder Merkmalen für Wertgegenstände, die eine richtungsabhängige optische Charakteristik aufweisen, die zur Prüfung eine optische Abbildungseinrichtung verwendet, die einen Bildpunkt zweidimensional abbildet, insbesondere in einen Ring, wobei die zweidimensionale Abbildung eine azimutale Intensitätsverteilung aufweist, die durch die Abstrahlrichtung des Bildpunkts bestimmt ist.The The invention relates to a device for testing valuables, in particular banknotes, and / or features for Valuables, the one directional have optical characteristics for testing an optical imaging device used, which images a pixel two-dimensionally, in particular into a ring, where the two-dimensional image is an azimuthal intensity distribution which is determined by the emission direction of the pixel is.
Die erfindungsgemäße Vorrichtung weist den Vorteil auf, daß durch eine einfache Auswertung der Intensitätsverteilung des abgebildeten Bildpunkts eine Überprüfung auf das Vorhandensein des Merkmals mit richtungsabhängiger optischer Charakteristik möglich ist. Dadurch wird die Überprüfung der Echtheit des Wertgegenstands in einfacher Weise ermöglicht.The inventive device has the advantage that by a simple evaluation of the intensity distribution of the imaged Pixel a check on the presence of the feature with directional optical characteristic possible is. This will verify the authenticity of the object of value in a simple manner.
Weitere Vorteile der vorliegenden Erfindung werden nachfolgend anhand von beigefügten Figuren näher erläutert und beschrieben.Further Advantages of the present invention are described below with reference to attached Figures closer explained and described.
