摘要：

Based on the relation between the frequency shift in Brillouin back-scattering light and the strain of the optical fiber, a new fully distributed fiber optical strain sensing system is proposed. This scheme is based on Brillouin optical-fiber frequency domain reflectometry(BOFDR). A new measurement is reported by utilizing fiber Bragg gating Fabry-Perot interferometer (FBGFPI) to directly separate the Brillouin signal. The experimental setup and results are presented. The primary experimental results confirm this configuration is feasible.
