We report a birefringent fiber remote strain sensor which is based on the FMCW technique and simply consists of two pieces of elliptical-core single-mode birefringent fiber. The first piece of fiber is used as the lead-in/lead-out fiber which is insensitive to environment, and the second one is used as a strain sensing fiber probe which is sensitive to the strain of itself with 2 microstrain resolution. The advantages of the sensor, such as large dynamic measurement range, long environment-insensitive leading-in/lead-out fiber and long strain sensing probe ar demonstrated in this experiment.
