Abstract :
We propose a fiber Bragg grating (FBG) Fabry-Perot cavity sensor consists of a pair of FBGs written directly into the same photosensitive fiber. Laser pulse launched into the cavity produces a group of reflection pulses. The power ratio of the first two reflection pulses could be detected for sensor measurement.
