Concurrent studies on artworks by digital speckle pattern interferometry and thermographic analysis
2016
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.
