Abstract

A processing scheme able to obtain any arbitrary intragrating strain distribution of a fiber Bragg grating (FBG) is proposed and demonstrated. The processing method employs just the intensity of the FBG reflection spectrum to obtain its deformation profile by combining a geometrical processing scheme with the particle swarm optimization technique. The technique has been evaluated using several spectra generated from very heterogeneous strain distributions and with a real spectrum obtained from a 5 mm length FBG under an asymmetric perturbation. The achieved results exhibit a good spatial resolution (Δ0.5mm) and repeatability.

Fig. 1.

Spectrum of a uniform FBG under the desired perturbation (solid line) is compared to the corresponding spectrum of a PSO candidate vector (dotted line). The error is computed using the main peaks of both spectra (crosses and circles) and the overlap under both curves.

Original strain profile is compared to PSO outputs for two different spatial resolutions (top). Best spectra for both resolutions are compared to the desired spectrum (bottom).

Part of the FBG is immersed in thermal paste while the rest is exposed to the air. The temperature increase is provoked by a Peltier heater.

Measured and a synthetic spectra obtained from a PSO output (top). Different PSO outputs and their averaged value (bottom).
