Abstract
(DE)
Die Erfindung betrifft eine Inspektion von Behältern auf Verunreinigungen, die eine Strahlungsquelle aufweist. Die Strahlungsquelle ist ausgebildet, Strahlung zu emittieren, die einen zu untersuchenden Behälter durchstrahlt. Die Vorrichtung weist ferner eine Detektionseinrichtung auf, welche ausgebildet ist die Strahlung zu detektieren, welche von der Strahlungsquelle emittiert wurde und den Behälter durchstrahlt hat. Die Vorrichtung weist auch eine Auswerteeinrichtung auf, die ausgebildet ist die von der Detektionseinrichtung detektierte Strahlung auszuwerten. Im optischen Weg zwischen der Strahlungsquelle und der Detektionseinrichtung ist ein Identifikationselement angeordnet, welches ein optisches Wasserzeichen aufweist.
(EN)
The invention relates to an inspection of containers for impurities, using a radiation source. The radiation source is designed to emit radiation that radiates through a container to be examined. The device also comprises a detection element which is designed to detect the radiation that has been emitted by the radiation source and has radiated through the container. The device further comprises an evaluation element which is designed to evaluate the radiation detected by the detection element. An identification element comprising an optical watermark is arranged in the optical path between the radiation source and the detection element.

L'invention concerne un dispositif d’inspection de contenants pour rechercher des impuretés, ce dispositif présentant une source de rayonnement. La source de rayonnement est conçue pour émettre un rayonnement qui traverse un contenant à examiner. Le dispositif présente en outre un système de détection qui est conçu pour détecter le rayonnement qui a été émis par la source de rayonnement et qui a traversé le contenant. Le dispositif selon l’invention présente par ailleurs un système d'évaluation qui est conçu pour évaluer le rayonnement détecté par le système de détection. Un élément d'identification qui présente un filigrane optique est disposé sur le chemin optique entre la source de rayonnement et le système de détection.
