Non linear imaging techniques (SHG, THG and MPEF) are implemented, as high resolution, non-destructive diagnostic tools for Cultural Heritage studies.
Non linear image contrast modalities (Multi Photon Excitation Fluorescence, Second Harmonic Generation, Third Harmonic Generation) have been proved to be powerful diagnostic tools for Cultural Heritage (CH) studies. These high resolution techniques have the potential to provide new information for the exact thickness determination and composition identification as a function of depth of different multi layer Cultural Heritage objects. Specifically, fresh and artificially aged varnish protective layers, pigments, lining glues and corrosion layers of silver based artifacts have been investigated. Furthermore, this femtosecond laser based approach (non linear microscopy) has been implemented for assessing in depth modifications induced during laser cleaning of modern paintings.
The non-destructive nature and the reduced data acquisition time of these imaging methods make them ideal diagnostic tools for in situ applications, facilitating the exact control of any cleaning interventions.
