Peak-search algorithm for center wavelength detection in fiber Bragg gratings
In order to find a better peak-search algorithm for the center wavelength detection in Fiber Bragg Grating(FBG)
the compilation and debugging of 9 peak-search algorithms for FBG demodulation systems are completed by using the LabVIEW technology and MATLAB and their parameters and advantages and disadvantages are analyzed and compared.On the basis of error analysis of the simulated and measured FBG signals and in connection with the experimental study and algorithm simulation
the algorithm errors and the related influencing factors are given.The results show that the optimal peak-search algorithm is the Gaussian fitting algorithm.
