Abstract Book, 29th ENFSI European Paint, Glass and Taggants Expert Working Group Annual Meeting, Brussels – Belgium, pp. 24-25, 2024. Non-destructive analysis of 3D objects is very important for forensic science and complex multimodal non-destructive analysis and characterization of 3D objects are a great challenge in the field of forensics and objects of art analyses. One of the options is the use of robotic scanners. A new system is currently being developed that integrates the existing X-ray scanner with other analytical modalities (XRF, XRD, multispectral imaging and others). The development of this system is currently being finalised in cooperation with Radalytica company. System is based on Radalytica’s multi-robot imaging platform, referred to as RadalyX. System measures nearly all conventional 2D and 3D trajectories of X-ray imaging with precisely calibrated and repeatable geometrical accuracy leading to a spatial resolution of up to 50 μm. System opens the door to explore new approaches to both 2D and 3D X-ray imaging, especially in combination with photon-counting detectors. Platform allows combining several imaging modalities with any required number of robots. Such modalities range from visible light imaging, UV, IR, to 3D surface profiling, air-coupled ultrasound to 2D X-ray imaging, and CT. The key parts of the scanner are two robotic stations. One robot carries an X-ray tube whose emission spot size range is 8 – 40 μm, and the operating voltage range is 10 – 130 kVp, and the other one holds a photon-counting imaging detector of the Widepix MPX3 family. Robots can move and rotate freely about the sample in a precisely synchronized movement. It provides almost absolute flexibility of viewing angles. The very high sensitivity, spatial resolution, and dynamic range of the used detectors enable us to push the X-ray image quality to its physical limits. System is equipped with accurate geometrical calibrations that allow positioning both robots precisely yet arbitrarily. Therefore, the robots can be moved to different locations during on-site inspections. System is equipped with 6-joint robotic arms that can position the detector and X-ray tube independently and freely around the scanned objects. The robotic arms are functional scanning elements for both 3D translation and rotation. They are used to measure the CT projections at different angles and positions. This flexibility of positioning enables new types of scanning trajectories, or even a combination of 2D scan strategies at multiple angles and positions to form optimal CT projections given the part accessibility and inner structure.
