Simulation and Identification in Thermography
Thermography is used for nondestructive testing of different materials in order to detect imperfections of the material. The numerical simulation of the temperature evolution in pulse thermography is difficult due to the important boundary layers. We develop analytically supported adaptive numerical simulation methods for the reliable simulation of thermography of concrete, and model both heating procedure and initial temperature profile in order to reproduce measurements.
Additionally, we develop fast, heuristic reconstruction algorithm providing quantitative data about defect location and shape.
