Abstract
The description refers to a device for the sensing of the D-dimensional data of an object, comprising a source which emits a particle beam or a travelling wave, either of which penetrates the object to be sensed and is attenuated by it depending on the D-dimensional structure of the object, and a (D-1)-dimensional sensor for the particle beam of the travelling wave, from whose output signal an evaluation unit calculates the D-dimensional structure of the object. The invention is characterized by the fact that the particle beam of the travelling wave is a divergent beam or a divergent field and that the source and the object are moved in planes relative to each other and which are parallel to each other and to the sensor plane.
