Interrogation technology for quasi-distributed optical fiber sensing systems based on microwave photonics
摘要
Abstract
Quasi-distributed fiber sensing systems play an important role in the fields of civil engineering, en-ergy surveying, aerospace, national defense, chemicals, etc. Interrogation technology for quasi-distributed fiber sensing systems based on microwave photonics is widely used in high-speed and high-precision signal demodulation and sensor positioning in optical fiber multiplexing systems. Compared to conventional optical wavelength interrogation, this technology greatly improves system demodulation rate and compensates for the defects of traditional sensor positioning methods. This paper introduces the recent research progress of quasi-distributed fiber sensing interrogation technology based on microwave photonics; compares and ana-lyzes the advantages and disadvantages of several existing microwave demodulation systems from the per-spective of their fiber grating quasi-distributed sensing and fiber Fabry-Perot quasi-distributed sensing sys-tems, respectively; and provides a summary of the prospective direction of future research in quasi-distrib-uted fiber sensing interrogation technology based on microwave photonics.关键词
