    Abstract

    A theoretical investigation on two techniques for the interrogation of fiber Bragg gratings (FBG) is reported. We compare two methods for decoding the Bragg wavelengths of gratings: the Fast Fourier Transform (FFT) processing and a parametric frequency estimation method called MUSIC. Results demonstrate that the second technique has advantages over the first one.
