The New Fiber-Optic Stain sensor

In This paper,we introducedA new fiber-optic strain sensor with white light interferometric principle based on FabryPerot,which is capable of providing measurement for the building strain. The signal processing of system is that the optical signal wavelength is modulatedInthe Fabry-Perot cavity,and is demodulated during the optical-electricity transform. Compared with a common optical fiber strain sensor,it has more advantages,such as low cost,high stability,and high antiinterference. The resolution of the fiber-optic stain sensor is up to 1μ ε within the test range being ±5000 με.The fiber-optic strain sensor system made up ofThis fiber-optic strain sensor is put into useInmany fields for monitoring inreal time and intelligent evaluating.
