Obtaining materials contrast is achieved by placing a Multi- Absorption Plate (MAP) in front of the detector . The MAP is a 3D, periodic structure providing different degrees of absorption of the X-ray beam locally. This affects the spectrum of X-rays hitting any given pixel of the detector and allows energy-dependent information to be recovered, and thus material information to be obtained.
For high-volume inspection, increased sensitivity to small structural and/or materials deviations from “normal” product can be obtained by building a mathematical model of “normal” product and allowed variability, based on the materials information obtained using the MAP.
Test cases are presented, showing applications of this technology in different areas, including electronics / industrial / security inspection, medical applications and contaminant detection in food products.
