摘要： The invention relates to a collimator with adjustable focal length, especially for use in X-ray testing devices whose operating principle is based on diffraction phenomena in an object. Fixed focal length collimators used in such X-ray testing devices have to be displaced over a large range. The aim of the invention is to reduce the range of displacement. For this purpose, the collimator has at least two diaphragms having respective substantially circular slots arranged about a common center axis, wherein at least one diaphragm can be displaced along the center axis.

摘要： A method for improving the ability to recognize materials in an X-ray inspection system is provided that includes the steps of recording at least two absorption X-ray images of an object to be examined at different energies, mathematically modeling the object by a number of layers assuming a particular material for each layer, wherein an absorption value describes the absorptivity of a layer, the number of layers is less than or equal to the number of X-ray images and at least one layer is assumed to be a material to be recognized during the inspection, decomposing the absorption value of each layer into a path-dependent factor and an energy-dependent factor, calculating the path-dependent factors for all layers from the absorption X-ray images using the absorption equation, calculating at least one synthetic image from the sum of all layers of the product of the absorption values and the weighting factors, evaluating the synthetic image.

摘要： In an inspection device for inspecting objects for explosives and other items prohibited for travel, particularly in carry-on baggage, a transport shaft (101) where there is little space, has incorporated thereabout radiation sources (10, 20, 30), which generate at least three beams (FX1, FX2, FX3) at which are directed at corresponding linear detectors (11, 21, 31). This transport shaft (101) is extended by incorporation of equipment or system components (3, 4, 40) that are not part of the inspection system (100), or by additional system components (4, 40) being integrated into a housing (103) of the inspection device (100), with a necessary radiation protection for the inspection device in compliance with radiation protection regulations being provided by a shielding (102) placed on or around a piece of equipment or its system components (3) already existing in the transport system (1), ideally in front of the transport shaft (101).
