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.}, publisher = {SPIE Society of Photo-Optical Instrumentation Engineers}, publisher = {Proceedings of SPIE, 2004, vol. 5502, 492-495}, publisher = {Second European Workshop on Optical Fibre Sensors, Santander, 2004}, title = {Application of the fast Fourier transform and parametric frequency estimation for the measurement of the Bragg wavelength of interferometrically interrogated fiber Bragg grating sensors}, author = {Díaz Lucas, Silvia and Jáuregui Misas, César and López Amo, Manuel and López Higuera, José Miguel}, }
