The forensic field requires versatile equipment for non-destructive characterization, analysis and inspection of 2D and 3D objects. The robotic scanner introduced here allows transmission X-ray imaging and mapping of individual photons with high-sensitivity and -resolution detectors. The broad capabilities of X-ray diffraction (XRD) imaging are now being complemented by X-ray fluorescence point analysis and mapping, multispectral macro imaging, and multispectral XRD analysis.

University of Illinois Physics Professor Paul Kwiat and members of his research group have developed a revolutionary new tool for precision measurement at the nanometer scale in scenarios where backgr...
