Abstract
Frequency shift in Brillouion back-scattering light can be changed when strain is exerted to an optical fiber. Brillouin scattering can be used to measure strain in distributed manner. A new fully distributed fiber optical strain sensing is proposed based on Brilliouin optical-fiber frequency domain reflectometry (BOFDR). A new measurement is reported by utilizing fiber Bragg grating Fabry-Perot interferometer (FBGFPI) to directly separate the Brilliouin signal. The experimental setup and result are presented. Primary result confirms this configuration feasible.
