| 摘要 |
The invention relates to a method and a device for monitoring the surface state of components, the surfaces of which comprise multiple layers, in order to thus detect different types of outer damage in a spatially differentiated manner. The method has the steps of illuminating at least some portions of the surface of at least one component in a broadband or narrowband manner by means of electromagnetic radiation using a lighting unit (26), detecting the electromagnetic radiation reflected by the component using a receiving unit (25), and evaluating the captured detection in a frequency-selective manner using an evaluating unit (21) such that damage to at least one component surface layer can be ascertained using the frequency-dependent absorption behavior or fluorescence behavior (15, 16, 17) of said component surface layer. |
