Abstract
Using photothermal measurements as a new NDE method opens an application field of increasing interest for the predictive maintenance of plants and components. As this high resolving method of micro-NDE especially applies to the near-surface range of materials, it should be able to deduce lifetime information. From the wide field of other applications, the study of the properties of surface caotings seems to be of special interest. Here, the utilization of a method which is sensitive in the near-surface range fits very well to the material's range of interests. Another promising field of application for this method is the characterization and qualification of new materials. This applies especially in cases where, standard NDE-methods cannot reveal the information needed.
