Laser and optical systems in analysis and diagnostics

                     

           The members of this Working Group (33 Institutions in 19 COST Countries) perform both fundamental and applied research on Laser and Optical techniques, systems and protocols for analysis and diagnostics of works of art and related activities (conservation, display, cataloguing). Fundamental research is largely devoted to the investigation of the potential of laser spectroscopic techniques (laser-induced fluorescence, LIF; laser-induced-breakdown spectroscopy, LIBS; Raman and Infrared spectroscopy) as tools for the characterisation of materials (e.g. LIF for pigments, binding media, varnishes; LIBS for pigments, stratigraphic analysis, on-line monitoring). Other laser-based techniques (3-D scanning, holography, holographic interferometry, Doppler vibrometry, fluorescence imaging either spectrum- or time-resolved or both), non-laser related optical techniques (diffuse-reflectance spectroscopy, colorimetry), and techniques borrowed from other fields, such as nuclear physics, are the subject of basic research investigating their potential for the characterisation of processes (ageing, restoration, ablation, weathering, structural alteration etc.).The most developed applied research activities are related to the monitoring of various conservation procedures including laser-assisted and traditional cleaning applications. Early detection of defects and damage is also carried out by a number of groups. These applications already concern real artefacts and valuable objects. Nevertheless the WG2 members have agreed to undertake a specific task on development and validation of protocols for structural defect diagnosis, for in situ chemical analysis and for analytical methodology before any intervention on artworks, facades and buildings.
