New Imaging Modality in Cultural Heritage

New Imaging Modality in Cultural Heritage

Scientists at the RCaH, in collaboration with CNR in Italy, have developed a new chemically specific method, micro-Spatially Offset Raman Spectroscopy (micro-SORS) for the non-invasive analysis of thin painted sub-layers in artwork, and applied it to the sub-surface analysis of the chemical constitution of historical mural paintings and sculptures originating from restoration sites in Northern Italy dating back several centuries. This is critically important for effective art restoration and preservation. The new method merges microscopy concepts with a conventional (macro-scale) SORS from the CLF ultrafast laser facilities at RCaH. See: http://www.stfc.ac.uk/3556.aspx.
