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.

A method for preparing a sample of organic material for laser induced breakdown spectroscopy (LIBS) may include obtaining granular organic material, forming a portion of the granular organic material into a sample pellet, and searing the organic material. The searing may include searing only an exposed end surface of the sample pellet on which LIBS analysis is to be performed. The method may include pressing the seared sample pellet to consolidate the material comprising the seared end surface.

A method for the X-ray inspection of products of a predefined product type including at least one first and one second component having different absorption coefficients for X-radiation. X-radiation with a spectral range is transmitted through the product to be examined. The X-radiation that has passed through the product is detected by means of a spectrally resolving X-ray detector. The X-ray detector assigns the X-ray quanta to a number of energy channels and generates image data which for each pixel include spectral values for selected or all energy channels and/or total spectral values for one or more groups of adjacent energy channels. At least on mapping rule is used to process the image data to form a total image, where each mapping rule is designed such that spectral values or total spectral values are mapped onto a total image value of an image point.

This X-ray phase imaging apparatus (100) includes a controller (5) that generates a dark field image (Iv) with respect to each of a plurality of relative positions between a subject (S) and an imaging grating (G1) changed by an adjustment mechanism (3) to acquire a contrast of a region of interest (ROI) in the dark field image (Iv), and controls the adjustment mechanism (3) to adjust a relative position between the subject (S) and the imaging grating (G1) based on the acquired contrast.

A test device for the irradiation of products which are fed into a housing along at least two tracks. At least one separate sensor is provided for each track in order to separately monitor the arrival at a target position selected individually for each track preferably within the housing of the test device.

Apparatus and method for detecting materials on a conveyor belt using multi-energy x-ray absorption imaging. A spectroscopic x-ray detector consisting of a line array of pixels receives x-rays from an x-ray source directed through the conveyor belt. The x-rays are attenuated as they pass through the belt and materials on the belt. The pixels each produce an energy spectrum of the received x-rays. The received energy spectrum of each pixel is related to the source x-ray spectrum to determine a measured attenuation, which is then related to an attenuation model that includes the attenuation coefficients of a set of preselected constituent materials expected to be in or on the belt. Mathematical regression is used to fit the measured attenuation to the attenuation model to find the thickness of each constituent material for each pixel.

A food processing system and a method for processing and batching food items conveyed by a conveyor means where the batches fulfil at least one target criteria including at least one weight target, including a first weight determining means for determining the weight of incoming food items, a batching system, a food item separation device positioned downstream in relation to the first weight determining means and upstream in relation to the batching system, and a control system for controlling the batching system and the food item separation device. The controlling including, repeatedly: monitoring the weight of the incoming food items, determining, based on the weight of the incoming food items, a prospect indicator indicating the prospect to meet the target criteria for the batches such that each batch fulfils the at least one target criteria, and comparing if the prospect indicator fulfils a pre-defined criteria.

A system for processing meat pieces includes a radiation inspection apparatus configured to receive a primary stream of meat pieces conveyed by a conveyor and to detect trim products containing undesired objects; a reject device; a control unit configured to operate the reject device using the detected undesired objects as an operation parameter such that the meat pieces containing the undesired objects are separated from the primary stream of trim products; an object remover configured to remove the undesired objects from the meat pieces separated from the primary stream of trim products; and a recirculation apparatus configured to receive the meat pieces after undergoing the object remover and recirculate it as a secondary stream into the radiation inspection apparatus. The secondary stream is separated from the primary stream, and the radiation inspection is configured to detect whether any remaining undesired objects are in the secondary stream.

In an X-ray inspection, a detection unit with a detector is provided. The detection unit detects transmitted amounts of the X-rays generated by an X-ray generator and transmitted through the object in each of n-number X-ray energy bins (n is a positive integer of 2 or more) which are set in advance to the X-rays, and outputs detection signals corresponding to the transmitted amounts. An information acquisition unit acquires, based on the detection signal, information showing a thickness t of the object and an average linear attenuation coefficient in a transmission direction of fluxes of the X-rays, in each of the energy bins. A pixel data calculation unit calculates, based on the acquired information, pixel data composed of pixel values each obtained by multiplying addition information by the thickness t. Addition information is obtained by mutual addition of the average linear attenuation coefficients in the respective energy bins.

Provided is an X-ray inspection apparatus that can inspect an object to be inspected with high sensitivity by using a multiple-stage X-ray sensor without widening a slit of a collimator, and can prevent the apparatus from becoming large-sized due to prevention of X-ray leakage. An X-ray inspection apparatus includes an X-ray irradiation portion having an X-ray tube generating an X-ray, an X-ray sensor having detection element arrays in a plurality of stages in a carrying direction, the detection element arrays each formed of a plurality of detection elements linearly arranged in a main scanning direction orthogonal to the carrying direction on a plane parallel to the carrying surface of an object to be inspected, a collimator restricting an X-ray irradiation region for the X-ray sensor, and an imaging condition input section that designates one or more detection element arrays to be used for inspection.
