Paper Abstract

We propose and experimentally demonstrate for the first time to the best of our knowledge the feasibility of an integrated hybrid optical fiber sensing system that efficiently combines distributed Brillouin optical frequency-domain analysis (BOFDA) technique with FBG-based quasi-distributed approach offering the possibility for simultaneous distributed and point-wise measurements. The highly integrated proposed scheme employs Gaussian shaped, broadband and low reflectivity apodized FBGs with a common narrow-band optical source and shared receiving unit over the same sensing fiber. A single mode optical fiber is used for distributed sensing and a pair of FBGs is employed for simultaneous pointwise measurements.
