Abstract

In this study distributed fiber optic sensors using commercial telecommunication and special sensor fibers have been studied and tested. A PC-compatible OTDR-card is used to obtain a portable measuring system. Especially the measuring of strain and stress in steel plates and bars is studied in comparison with strain gage measurements. The sensing of ice temperature with a special sensing fiber is also reported. Applications of the fiber sensors studied here are strain and stress measurements and crack detection in steel chambers and pipes especially at high temperatures (> 300 degree(s)C), and freezing detection of road structures.
