Wide-field, coherent scatter imaging for radiography using a divergent beam

A radiographic imaging system for detecting a material in an object to be analyzed, wherein the system comprises:

• a divergent source of partially monochromatic x-ray radiation, the divergent source configured to illuminate a wide field of an object with the partially monochromatic x-ray radiation;
• at least one scatter-rejection means for rejecting the x-ray radiation scattered by the object outside of a predetermined range of angles defined about a characteristic angle, the characteristic angle being a scattering angle about which a material of the object coherently scatters the partially monochromatic x-ray radiation;
• and
• at least one detector wherein each of the at least one detector is positioned to detect coherently-scattered radiation passing through a respective one of the at least one scatter-rejection means, the coherently-scattered radiation comprising the partially monochromatic x-ray radiation diffracted about the characteristic angle by the material if the material is present in the object.
