Description
Die Erfindung betrifft einen Scanner zur Erfassung unzulässiger Gegenstände in Prüfobjekten.The invention relates to a scanner to record impermissible objects in test objects.
Bei der Analyse der durchstrahlten Prüfobjekte stellt sich das Problem, daß u.a. auch Materialzusammensetzungen unterschieden werden müssen, um bestimmte Prüfobjekte identifizieren zu können. Dieses wird durch die Analyse der Strahlung nach Durchdringen des Prüfgutes in zwei unterschiedlichen Strahlungsenergiebereichen ermöglicht.When analyzing the radiated Test objects the problem arises that material compositions must also be distinguished in order to certain test objects to be able to identify. This is done by analyzing the radiation after penetrating the test material in two different radiation energy ranges.

Des weiteren ist es bekannt, die unterschiedlichen Strahlungsenergiebereiche durch die Verwendung zweier für die beiden Energiebereiche unterschiedlich empfindliche Detektorsysteme zu erreichen. Bei diesem System wird jedoch die notwendige Materialauflösung eingeschränkt, weil die beiden Strahlungsenergiebereiche nur bedingt getrennt werden können.Furthermore, it is known that different radiation energy ranges through the use two for the two energy areas have differently sensitive detector systems to reach. With this system, however, the necessary material resolution is restricted because the two radiation energy areas are only separated to a limited extent can.
Der Erfindung liegt die Aufgabe zugrunde, einen Scanner der eingangs genannten Art derart weiter zu bilden, daß die Materialauflösung unter Umgehung der genannten Einschränkungen verbessert wird.The invention is based on the object to further develop a scanner of the type mentioned at the beginning, that the material resolution is improved while circumventing the restrictions mentioned.
Gelöst wird diese Aufgabe durch die im Patentanspruch 1 aufgeführten Merkmale. Der Erfindung liegt die Erkenntnis zugrunde, daß bei einem Scanner der eingangs genannten Art mindestens zwei räumlich getrennte fächerförmige Röntgenstrahlbündel mit verschiedenen optimierten Energiebereichen realisiert werden können. Durch diese lokale Auftrennung der beiden Strahlenbündel durch die Anordnung zweier voneinander getrennter stabiler Strahlenquellen und einer zusätzlichen Möglichkeit einer unterschiedlichen Filterung wird ein großer Unterschied in der energetischen Verteilung der beiden Strahlenbündel erreicht, so daß eine verbesserte Materialauflösung erzielt wird, und weiter vorteilhaft die einzelnen Strahlenquellen und Filter als statische Elemente eine hohe Stabilität gewährleisten.This task is solved by those listed in claim 1 Characteristics. The invention is based on the finding that a scanner of the type mentioned at the beginning with at least two spatially separated fan-shaped X-ray beams different optimized energy areas can be realized. By this local separation of the two beams by arranging two separate stable radiation sources and an additional one possibility Different filtering will make a big difference in energy Distribution of the two beams reached so that a improved material resolution is achieved, and further advantageous the individual radiation sources and filters as static elements ensure high stability.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels des näheren erläutert.The invention is described below an embodiment of the closer illustrated in the drawing.
