Paper Abstract

Implementation of a strain tuned linear cavity EDF laser for interrogation of multiplexed FBG sensors is reported. A high-strength draw-tower FBG is used as the mechanically tunable element allowing for the wavelength sweeping of the laser. A simple algorithm to process the noisy acquired data and identify the peak of the FBG sensors spectra is proposed. These two techniques are able to improve the reliability of multiplexed FBG interrogation systems using mechanically tunable FBG and decrease the cost of systems that use conventional tuning elements in the optical circuit.
