title = "FMCW birefringent fibre strain sensor with two forward-coupled beams",
abstract = "This paper describes a new birefringent fibre strain sensor which is based on the FMCW technique. The sensor comprises a single length of elliptical core birefringent fibre with a mirror attached at the far end and a mode coupler in the middle. The strain variation of the fibre sensing probe can be measured by detecting the phase shift of the beat signal which is produced by two forward-coupled polarisation mode beams. The experimental results demonstrated that the sensor has many advantages, such as (i) high resolution (2 microstrain), (ii) large dynamic measurement range (5000 microstrain), (iii) large signal intensity and good signal contrast, (iv) long and length-adjustable sensing probe, (v) long and environment-insensitive lead-in and lead-out fibre, (vii) simple signal processing, and (vii) low cost.",
