A method and an apparatus for detecting unacceptable items in objects, such as in luggage, wherein a detector apparatus, functioning as a second detector stage is divided into a lower testing stage and a higher testing stage. In the lower testing stage, the coordinates of the object location are determined, and subsequently, a diffraction apparatus is moved to this location in the higher testing stage. In particular, X-ray diffraction can be employed to determine the explosive material of the item in the object. The diffraction apparatus comprises a collimator/detector arrangement, which is disposed to be adjusted height-wise and laterally in the higher testing stage, with a laterally-adjustable X-ray source, which is synchronized with the collimator/detector arrangement. The collimator/detector arrangement preferably has only one collimator and one detector. The collimator preferably has a conically-expanding ring slot, which simulates a predetermined angle ΘM of a scatter radiation.
A method for detecting an unacceptable item in an object comprising the steps of:
An apparatus for detecting an unacceptable item in an object, comprising:
The apparatus of claim 13, wherein said collimator additionally has a central blind-bore-like opening containing first and second exactly spaced detection devices.
The apparatus of claim 0 wherein the collimator/dector arrangement is oriented toward a primary beam of the source and aligned thereto using the first and second detection devices.
Dependencies are inferred from the claim text.
