A device is provided for inspecting objects, particularly pieces of luggage, for suspicious contents using electromagnetic radiation. The device includes a housing comprised of a support and a closable opening through which an object to be inspected can be placed on a receiving element; a source for electromagnetic radiation and a designated detector array, both of which are arranged in the housing such that an inspection area is located above the receiving element; a positioning aid, which indicates the inspection area to an operator; and an evaluation unit including a computer, where the radiation intensities measured by the detector array are evaluated with respect to suspicious materials.

Device and method for inspecting objects

A method for the detection of a specific material in an object (), especially in a piece of luggage, using electromagnetic beams, whereby the intensities of non-absorbed beams from at least three beam planes () in corresponding detector arrays () are measured and evaluated, using the following steps according to the invention: 1. generating an at least two-dimensional picture of the object () from the measured intensity values; 2. selecting one of the spatial regions displayed in the picture as a basis of the value of a material value, which is determined from intensity measurements, for examination; 3. determining at least one spatial-geometric value in the region to the examined from positional data of a two-dimensional picture and from intensity values using a stored value of a specific, absorption-influenced value of a suspected material. 4. determining, in addition, the corresponding spatial-geometric value solely from three-dimensional geometric values, which are determined from measured intensity values; and 5. comparing, directly or indirectly, values of the spatial-geometric values determined in steps 3 and 4, or values derived therefrom, in order to determine if the suspected material is actually present.

Method and device for detecting a given material in an object using electromagnetic rays

A method and an apparatus for detecting items in objects, such as in luggage, wherein a detector apparatus, functioning as a second detector 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 a predetermined angle &#x398;of a scatter radiation.

Apparatus and method for detecting items in objects

A diffraction apparatus ( ) for determining crystalline and polycrystalline materials of an item in objects, preferably in luggage, having a collimation/detector arrangement ( ) and an X-ray source ( ) and which is mounted to be adjustable in an X-ray testing machine ( ). The collimation/detector arrangement ( ) is adjustable in height relative to the X-ray source ( ), and the two are also laterally and synchronously adjustable via respective adjustment elements ( ). The collimator ( ) has a conically-expanding round slot ( ), which simulates a predetermined angle (&THgr; ) of a scatter-beam path.
