The purpose of the paper is to provide an analysis of the attitude exhibited by demodulation algorithms of Fiber Bragg Gratings (FBG) based on Cross Correlation methods. The Cross Correlation technique here considered is based on calculations performed in spectral domain. Its behavior against the peak-locking phenomenon has been analyzed and a way for attenuating it has been devised. The new Iterative Cross Correlation algorithm improves the FBG demodulation accuracy and precision, giving remarkably attenuated peak-locking amplitude.
