Advances in phase-sensitive optical time-domain reflectometry
文献摘要：
Phase-sensitive optical time-domain reflectometry (Φ-OTDR) has attracted numerous attention due to its superior per-formance in detecting the weak perturbations along the fiber. Relying on the ultra-sensitivity of light phase to the tiny de-formation of optical fiber, Φ-OTDR has been treated as a powerful technique with a wide range of applications. It is fun-damental to extract the phase of scattering light wave accurately and the methods include coherent detection, I/Q de-modulation, 3 by 3 coupler, dual probe pulses, and so on. Meanwhile, researchers have also made great efforts to im-prove the performance of Φ-OTDR. The frequency response range, the measurement accuracy, the sensing distance, the spatial resolution, and the accuracy of event discrimination, all have been enhanced by various techniques. Further-more, lots of researches on the applications in various kinds of fields have been carried out, where certain modifications and techniques have been developed. Therefore, Φ-OTDR remains as a booming technique in both researches and ap-plications.
