X-RAY DETECTOR APPARATUS AND APPARATUS FOR X-RAY INSPECTION OF PRODUCTS, IN PARTICULAR FOOD PRODUCTS

摘要

The invention relates to an X-ray detector device for a device for the X-ray inspection of products, in particular food, with at least one first line detector with a first discrete spatial resolution, which is used to detect broadband X-ray radiation along one or more parallel first detection lines transversely to a direction of movement of a relative movement between one to product to be examined and the X-ray detector device and which detects the X-ray radiation that has passed through the product to be examined over a predetermined detection width non-spectrally resolved and generates first image data, the first image data comprising a gray value for each discrete location, and with at least one second line detector with a second discrete spatial resolution, which is less than or equal to the first discrete spatial resolution, which the X-rays along one or more r parallel second detection lines, which run parallel to the first detection lines, detected discretely spectrally resolved over the specified detection width and generated second image data, the X-ray quanta for spectral resolution, depending on their energy, being assigned to a plurality of energy channels, and the second image data for each discrete location include a spectral value for each energy channel, and with an evaluation and control unit to which the first and second image data are fed and which is designed to evaluate the first and second image data in such a way that at least one predetermined feature of the product to be examined is carried out a combination of the information contained in the first and second image data with the first discrete spatial resolution is detected. The invention also relates to a device for x-ray inspection of products, in particular food, with such a radiation generating device.
