Paper Abstract

This paper describes a new distributed optical fiber stress sensor system which consists of a piece of birefringent fiber with a mirror at one end and whose principle of operation is based on the frequency modulation continuous wave (FMCW) technique. The intensity and the location of an applied stress can be determined simultaneously by detecting the amplitude and the frequency of the beat signal which is produced by two forward-coupled mode beams. The system was found to have the advantages of large signal intensity, good signal contrast, 1 meter resolution and up to 100 meters measurement range.
