New robotic tools for multimodal, non-destructive analysis and characterization of 2D and 3D objects

Original language description

The forensic field has until now been missing more versatile equipment for non-destructive characterization, analysis and inspection of 2D and 3D objects. Also, the need for increasingly frequent analysis of art forgeries, where non- destructive analysis is required, at least in the first step, is calling for a multimodal solution. A prototype device for robotic analysis, imaging and mapping of 3D objects is being developed and tested to be used in these areas. The system' s principle is integration of imaging and analytical technologies onto six-axis robotic arms which allow wide flexibility range concerning the sample size or shape. The system allows non-destructive examination of wide spectrum of samples with complicated curvatures. The new generation of X-ray imaging detectors provides a high picture quality with a spatial resolution level in the micrometre range in 2D or 3D imaging. The basic version of the robotic scanner allows transmission X-ray imaging and mapping of the individual photons with high sensitivity and resolution detectors. These detectors are the result of an intensive international cooperation led by the CERN laboratory in Geneva. The particular used type of imaging detectors allows to measure X-ray wave lengths [l]. From the changes in the X-rays spectrum after it has gone through the sample, it is possible to presume the elemental composition of the examined object. 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 kV, and the other one holds a photon-counting imaging detector of the Widepix MPX3 family [2]. 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. Differences in spectrum changes then reflect in the resultant image in the form of false colours. Another extension modality is XRD phase mapping which exploits properties the Timepix3 spectral imaging detector which records the position and energy of every detected photon as well as the time of detection. Regarding these properties, a monochromator can be left out from the XRD device [3]. The construction fundamentally simplifies the XRD device and allows integration with robots. The robotic scanner further allows scanning and mapping of crystallographic properties of the whole examined object on surface. This information is further combined with the XRF elemental mapping of the whole object. There exist many possibilities how to combine the XRF data with transmission maps and X-ray imaging data - a robotic scanner measures all analytical modalities in a common reference system. The system is supplemented with other modalities which allow to obtain more analytical data - VNIR, SWIR and the UV modules. The use of this information is very wide.
