Abstract
Optical fiber sensing has the advantages of immunity to electromagnetic interference, resistance to corrosion, light weight, small size, high resolution, and easy multiplexing, which has been widely used for various sensing applications,such as aerospace, petrochemical, electronic power, civil engineering, and biomedicine. The conventional interrogation schemes suffer from the problems of low resolution, low rate, and poor stability. To solve these problems, microwave photonics based sensing and interrogation technique has attracted extensive attention of the researchers. In this paper, a comprehensive and systematic overview of optical fiber sensing interrogation techniques based on microwave photonics is presented. Several microwave photonics based interrogation schemes and the corresponding operation principles are introduced, and the future development direction are also discussed.
