Coherent x-ray scatter imaging for foodstuff contamination detection

摘要: Using the novel technique of energy-dispersive X-ray diffraction tomography, measurements were made coherent scatter from various types foodstuff (chocolate, bacon, cherry jam, chicken breast) with their typical contaminants (macrolon, blue foil, stones/wood and bone, respectively). In addition, it is shown how use a window in spectrum allows cancellation contribution images, leaving only that contaminant. The extension to multicomponent systems, allowing arbitrary elimination unwanted materials possible. Taken together, these results indicate great potential analysis for contamination detection industry. By development more efficient geometries, using e.g. fan beam irradiation simultaneous acquisition spectra different voxels, requirements industrial mass production respect inspection time resolution are likely be met.© (1994) COPYRIGHT SPIE--The International Society Optical Engineering.
