Abstract
Detecting illegal drugs in mailed packages without opening the package is a challenge. X-ray diffraction tomography offers the potential capability of uniquely identifying illegal drugs within a package based on their atomic structure. To understand the separability of different drug classes, we generated a library of X-ray diffraction drug signatures and explored them using dimensionality reduction techniques. In addition, we used a compact, multi-modality fan beam Xray imaging system (combining transmission and X-ray diffraction) to distinguish oxycodone from non-prescription medicine when concealed within different types of containment.
