In recent years, the observation of the behaviour of components during the production process and over their life cycle is of increasing importance. Structural health monitoring, for example of carbon composites, is state-of-the-art research. The usage of Fibre Bragg Gratings (FBGs) in this field is of major advantage. Another possible area of application is in foundries. The internal state of melts during the solidification process is of particular interest. By using embedded FBGs, temperature and stress can be monitored during the process. In this work, FBGs were embedded in aluminium alloys in order to observe the occurring strain. Two different FBG positions were chosen in the mould in order to compare its dependence. It was shown that FBGs can withstand the solidification process, although a compression in the range of one percent was measured, which is in agreement with the literature value. Furthermore, different lengths of the gratings were applied, and it was shown that shorter gratings result in more accurate measurements. The obtained results prove that FBGs are applicable as sensors for temperatures up to 740 °C.

Zusammenfassung Dieser Artikel beschreibt ein neuartiges fluoreszenzbasiertes Messsystem zur Qualitätsüberwachung von fluoreszierenden Materialien. Das Messsystem beinhaltet zwei unterschiedliche optische Pfade. In einem wird eine abbildende und im anderen eine spektral aufgelöste Aufnahme einer Messfläche erzeugt. Eine Anwendung ist die Überprüfung von viskosen Materialien. Hier kann durch die Kombination der beiden Abbildungen die Art, Position und Größe von Verunreinigungen bestimmt werden. Das Messsystem ermöglicht statische und bewegt Messungen. Durch die Verwendung von Standardkomponenten ist es kostengünstig und an viele viskose und nicht-viskose fluoreszierende Materialien anpassbar.
