.Reconstruction of strain distribution in fiber Bragg grat-ings with differential evolution algorithm[J].Optoelectronics Letters,2008,4(6): Reconstruction of strain distribution in fiber Bragg grat-ings with differential evolution algorithm Abstract:       Differential evolution algorithm is used to solve the inverse problem of strain distribution in tibet Bragg grating (FBG).Linear and nonlinear strain profiles are reconstructed based on the reflection spectra. An approximate solution could beobtained within only 50 rounds of evolutions. Numerical examples show good agreements between target strain profilesand reconstructed ones. Online performance analysis illuminates the efficiency and practicality of differential evolutionalgorithm in solving the inverse problem of FBG.
