X-ray grating interferometry is implemented using synchrotron light sources, which produce very intense and highly coherent X-rays. By introducing a pair of gratings, called phase gratings (G1) and absorption gratings (G2), between the source and detector, the beam intensity is modulated and the wave phase is analyzed, thus obtaining additional information to the absorption signal (ABS): a differential phase contrast signal (DPC) and a dark field signal (DF).[\/vc_column_text][vc_empty_space][vc_single_image image=”4800″ img_size=”full” qode_css_animation=””][vc_empty_space][vc_column_text]However, this technique can also be used with conventional X-ray sources, such as those for medical or industrial radiography, optimizing coherence conditions through the addition of an absorption grating (G0) near the source.<\/p>\n

MAGNUM applies this technology to the food industry through a system capable of:<\/p>\n
