Paper Abstract

This paper describes a novel optical fiber remote strain sensor which is based on the FMCW technique and consists of only one single piece of single-mode birefringent fiber. The lead-in and lead-out fibers which are simply separated from the strain sensing fiber by two short twisted fiber portions are insensitive to environmental changes so that the sensor can remotely detect the strain variation of a distant construction. Other advantages of the sensor, such as no fiber junctions, no feedback light, long sensing fiber, higher resolution (4 microstrain) and large dynamic measurement range (5000 microstrain) are demonstrated in this experiment.
