Abstract
Performance of a thermal line scanning nondestructive evaluation syste m for low-diffusivity materials was studied using PVC samples having f lat bottom holes. The measurements were also simulated numerically, an d these results were compared with the experimental results. Multiple scans over the damaged area were found to significantly improve the co ntrast in thermal images.
