Application of Quantitative and Qualitative Mapping of Materials in Forensic Practice

Original language description

Standard quantitative or qualitative mapping is widely used in forensic practice in many examinations. Further, mapping can be used for a detailed study of paint layers on paintings to determine authenticity of works of art. Current markets, especially the one with modern art, are flooded with counterfeits identification of which is rather difficult and requires initial non-destructive techniques – photography and video analysis, multispectral imaging (from the UV spectrum up to the infrared), X-ray imaging and, further, mobile analytical techniques – point analysis and mapping using XRF and Raman spectroscopy. Using this information, sampling locations for micro samples are determined, where the mapping techniques are further applied from the SEM/EDS/WDS, micro XRF to mapping in the Raman spectrum. A prototype device for robotic analysis, imaging and mapping of 3D objects in forensic area is being tested to be used in the aforementioned 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 micrometer range in 2D or 3D imaging. The use of this information is very wide. The individual image layers can be switched on and arbitrarily combined with the obtained maps. In the forensic field, the use is rather extensive – not only for works-of-art analysis but also in tools and marks examination, forensic defectoscopy and metallography and other areas.
