- In this contribution, the development and application of optical and thermographic methods for the nondestructive evaluation of delaminations, cracks and further substructures in Connection with bulging is presented.
Since delaminated fagade elements show geometric as well as thermal anomalies, surface geometry and defects beneath the surface were investigated. As methods, Stereo photogrammetry, a tracking based method for tactile recording of geometric 3D data and active thermography were used. Two case studies were assessed with a combination of these methods: the plaster scratches at the Magdeburg Cathedral and a mural painting in Cobbelsdorf, both located in Germany. While the plaster scratches have been investigated by artificial heating with an infrared radiator, the rural painting was tested by analysing the temperature increase due to solar heating.
