CT scanner comprising a scanning conveyor (9) mounted on a supporting structure and configured to move an object (3) for CT examination forward through a scanning area (8), an input conveyor (10) configured to convey the object until the scanning chamber (2), and an output conveyor (11) configured to convey an object (3) out of the scanning chamber (2), wherein the input conveyor (10), the scanning conveyor (9) and the output conveyor (11) are configured to move forward the object (3) placed on a supporting unit (19) mechanically detached therefore, and wherein the scanning conveyor (9) is configured to rotate the supporting unit (19) and the object (3) on themselves as they travel through the scanning area (8). The input conveyor (10) and the output conveyor (11) are fitted with shields configured in such a way as to intercept all x-rays emitted from the scanning area (8) which escape from the scanning chamber (2) towards the conveyors.

An X-ray imaging system includes an X-ray detector; a plurality of X-ray sources configured to illuminate the detector from different perspectives; a shutter in a transmission plane between each X-ray source controlling transmission of X-rays from each X-ray source to the detector; and a processor configured to receive and process X-ray data from the detector. The shutter may be configured to illuminate the detector alternately with each X-ray source. The processor may determine 3D information about an object from the processed X-ray data. Also provided are methods for processing X-ray data and different embodiments of shutters to alternately illuminate X-ray detectors.

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 μ 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 μ in the respective energy bins.

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 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.

A scanner comprises an electromagnetic wave source; a collimator positioned to alter the electromagnetic waves emitted from the electromagnetic wave source into an electromagnetic beam; and a detector positioned to measure one or more levels of electromagnetic energy of the electromagnetic beam, wherein a collimator element is spatially adjustable in at least one axis via one or more adjusting mechanisms to change the one or more levels of electromagnetic energy measured the detector.

System and method of detecting infestation in agricultural products is disclosed. In one embodiment, an infestation detection system captures hyperspectral imaging data and depth imaging data for a plurality of points on an agricultural product upon directing a light source at the agricultural product. The system analyses the captured imaging data to derive morphological details as well as spectral signatures for complete 360° view of the plurality of points on the agricultural product. In an embodiment, the spectral signatures may be corrected for one or more pixels associated with the plurality of points in the agricultural product by integrating the hyperspectral imaging data with the depth imaging data. The system further classifies one or more regions of the agricultural product based on matching of spectral signatures for the one or more pixels with pre-defined spectral signatures stored for a plurality of agricultural products, and accordingly detect infestation.
