Abstract

We utilize Digital Speckle Pattern Interferometry and Square Pulse Thermography Analysis, as complementary tools for cultural heritage artifacts diagnostics. The concurrent utilization of two methods provide the possibility to complement and validate the effective understanding of each individual technique results, that are not always easy to interpret. Both techniques are non-invasive and can be applied on almost any type of archaeological finds, providing relevant information about their state of conservation. The applications include the whole structure analysis, as well as the detection of detachments, micro-cracks, hidden damages. The diagnostic investigation can be carried out before, during and after a restoration. It is also possible the real time monitoring of the behavior of the object according to the environment thermo-hygrometric changes. Examples of analysis on different artworks are illustrated.
