We propose an efficient model-based signal processing approach for
optical fiber sensing with fiber Bragg grating (FBG) arrays. A position
estimation based on an estimation of distribution algorithm (EDA) and a
reflectivity estimation method using a parametric transfer matrix model
(TMM) are outlined in detail. The estimation algorithms are evaluated
with Monte Carlo simulations and measurement data from an incoherent
optical frequency domain reflectometer (iOFDR). The model-based approach
outperforms conventional Fourier transform processing, especially near
the spatial resolution limit, saving electrical bandwidth and
measurement time. The models provide great flexibility and can be easily
expanded in complexity to meet different topologies and to include
prior knowledge of the sensors. Systematic errors due to crosstalk
between gratings caused by multiple reflections and spectral shadowing
could be further considered with the TMM to improve the performance of
large-scale FBG array sensor systems.
