The characterization of the double fiber Bragg grating fiber ring laser and its applications in a real time fiber sensing system
We demonstrate a fiber sensing system by using a fiber resonator which is formed by two fiber Bragg gratings. It is able to measure real time strain and stress directly by the variation of the intensity of the output power due to the modulation in the fiber resonator. It shows that recording of the strain variation can be achieved as high as 2K Hz. The frequency response, signal noise ratio, and maximum range of the sensing system are studied with various reflectivity of the FBG, and the coupling ratios of the couplers used in the system.
