title = "FMCW birefringent fiber strain sensors based on sagnac rings",
abstract = "This paper discusses different configurations of polarization maintaining fiber Sagnac ring strain sensors based on FMCW technology. Each sensor consists of a frequency-modulated single mode laser, a 100 meter length of single mode birefringent fiber ring and PIN photodiode detector. In each case, two opposite propagating beams in the fiber are employed to sense the variations in length due to strain, although the generation of the beat signal is different in each case. The final sensor specifications are very similar as both exhibit high resolution, large dynamic measurement range, large signal intensity, good signal contrast and long sensing fiber.",
