Patent number: 7579580Abstract: An optical sensor (1) with a light beam (7) created by a pulsed primary light source (5), which light beam is reflected at a surface (13) of an object and is recognized by a detector. In order to mask interfering effects, which might develop due to diffused light of the light beam (7), a compensation light source (25) emits a light cone during station breaks in operation of the primary light source (5), which includes the diffused light range of the light beam (7) of the primary light source (5). In this way, objects within the diffused light area create a compensation light portion, which prevents the activation of the sensor output merely by the diffused light of the light beam (7).Type: GrantFiled: March 31, 2006Date of Patent: August 25, 2009Assignee: Baumer Electric AGInventor: Peter Halter

Patent number: 6784441Abstract: A manually controlled sensor for authenticity identification of luminescent identification features on documents is described, in which the identification feature is illuminated with an excitation wavelength and may respond at a different wavelength, with the response wavelength being detected and evaluated by a radiation receiver. In order to improve the sensitivity and to comply with the safety at work regulations, a focused beam (31, 32), which is emitted from a beam source (1), is converted by focusing optics (2, 3) in such a manner that a scanning bar (22), which is approximately in the form of a line, is projected on the surface of the object (5) to be investigated, which causes the identification region (21) which is arranged on the object (5) to fluoresce in a luminescent manner in at least one subregion, and the luminescence signal produced in this way is passed via detection optics (9, 9′, 10) to an evaluation unit (11), which evaluates the luminescence signal.Type: GrantFiled: July 3, 2001Date of Patent: August 31, 2004Assignees: Bundesdruckerei GmbH, Baumer Electric AGInventors: Benedikt Ahlers, Roland Gutmann, Arnim Franz-Burgholz, Anett Bailleu, Manfred Paeschke, Peter Halter, Hans Zerbel, Uwe Weber

Patent number: 6741336Abstract: A sensor is proposed for authenticity identification of luminescent identification features on documents, in which the identification feature is illuminated with an excitation wavelength and may respond at a different wavelength, with the response wavelength being detected and evaluated by a radiation receiver. The focused beam emitted from a beam source is converted by focusing optics in such a manner that a scanning line, which is approximately in the form of a bar, is projected on the surface of the document to be investigated, which causes the signet, which is arranged on the document, to fluoresce at least in one subregion, and the fluorescence signal produced in this way is passed via detection objects to an evaluation unit, which evaluates the fluorescence signal.Type: GrantFiled: June 4, 2001Date of Patent: May 25, 2004Assignees: Bundesruckerai GmbH, Bauner ElectricInventors: Benedikt Ahlers, Roland Gutmann, Arnim Franz-Burgholz, Anett Bailleu, Manfred Paeschke, Peter Halter
