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： This invention concerns an apparatus to transilluminate objects. In known apparatus (1) there are two radiation sources (10, 20) in a transport path of a transport device (3), below to the right and left, as well as a third radiation source (30) arranged horizontal to the transport path (3), with the two radiation sources (10, 20) lying close together, one behind the other. Three detector apparatus (11, 14, 31) are arranged opposite these radiation sources (10, 20, 30). Thus, a so called multi-view from three beam directions is created, with beam paths (FX1.1, FX2.2, FX3) extending perpendicular to a transport direction. Contrary thereto, in the solution described herein, various radiation beam paths (FX1.1, FX1.2, FX2.1, FX2.2, FX3) cross so that not every beam radiation path extends perpendicular to the transport direction. This has the advantage that the apparatus can be structured in a space saving manner. In a particular embodiment, using three radiation sources (10, 20, 30) and five detector apparatus (11, 12, 21, 22, 31) in a single apparatus, an object (4) to be transilluminated is transilluminated from five different beam directions during its transport through a transillumination space (5) and a quasi 3-D (three-dimensional) model (6) of the object (4) is thereby, simultaneously created. In this regard, two of the detector apparatus (12, 21) are arrange angularly displaced from one another, within one another, to be directed toward corresponding rays (FX1.2, FX2.1) of the beam radiation sources (10, 20). With the help of signals obtained therefrom, in addition to the absorption rate, also the thickness or volume, and therefrom the density, of the items (4.1) in the object (4) can be determined. From the absorption rate and the density, the type of material found in the object (4) and the transilluminated items (4.1) can be exactly determined.
