X-ray detector device and device for the X-ray inspection of products, in particular foodstuffs

摘要

An X-ray detector device for a device for the X-ray inspection of products includes a first line detector with a first discrete spatial resolution, a second line detector with the same or lesser second discrete spatial resolution, and an evaluation and control unit. The first line detector is operable to capture X-radiation in a non-spectrally resolved fashion along a first capture line transverse to a product movement direction to generate first image data. The second line detector is operable to capture the X-radiation in a spectrally resolved fashion along a second capture line parallel to the first capture line to generate second image data. The evaluation and control unit is operable to evaluate the first and second image data to detect at least one predefined feature of the product with the first discrete spatial resolution by combining the items of information contained in the first and second image data.
