The Comparison and Analysis of Typical Peak-detection Algorithms in Fiber Bragg Grating Sensor System

Based on the platform of virtual instrument LabVIEW,this paper is to detect peaks of original signal respectively with power-weighted algorithm,Gaussian fitting algorithm,Gauss-polynomial fitting algorithm,a general polynomial fitting algorithm and Gaussian non-linear curve fitting algorithm,and compare their error means and standard deviations.Comparing the deviations with the changes of the wavelength resolution,window size,SNR,and experimental verification is carried on finally.Gaussian fitting algorithm is proved to be the best peak-detection algorithm by theory,simulation and experiment.
