摘要：
Frequency-derived distributed optical-fiber sensing is a powerful and convenient method for measuring the spatial distribution of birefringence in a high-birefringence fiber. The method relies on the special statistical characteristics of Rayleigh backscatter for its action, and these are analyzed in the context of the sensing arrangement, with an emphasis on the physical mechanisms. Implications for system design are also discussed.
