【Abstract】 The distributed optical fiber sensing technology is the hot off the press in the optical fiber sensing field in recent years. The research achievements are introduced, including the full distributed fiber sensors based on the optical fiber backscattering time domain and frequency domain reflection techniques, the optical fiber Rayleigh scattering polarization sensitive optical time domain reflection techniques, the long distance optical fiber interference techniques, and the quasi-distributed fiber sensors based on the nonidentical and identical fiber Bragg gratings multiplexing techniques. Moreover, the working principles, characteristics and performance of the distributed optical fiber sensing systems, and their applications in the civil engineering structures, aeronautics and astronautics, shipping industry, power industry, petrochemical industry and medicine areas are comprehensively discussed.更多还原
