Active Thermography II

Development of a measuring instrument for a non-destructive analysis of works of art and cultural assets based on the procedure of thermal testing of coatings


Active thermography is an imaging, non-contact and non-destructive testing method that is employed in industry to localize, visualize and quantify hidden damage on coated surfaces. In a preparatory CTI feasibility study, we have now been able to demonstrate that this method also has great potential in the fields of conservation and restoration. Numerous applications have been proven, such as detecting delamination on a paint layer, laquer layer or polychrome surfaces. Furthermore, a measuring instrument has been developed for the practical application of this procedure on works of art and cultural assets. As part of the current CTI research project, this is to be further developed specifically to produce a simple-to-use measuring instrument that may be utilized by conservators.
