摘要
Adaptive simulated annealing algorithm used for determining the strain profile along a fiber Bragg grating (FBG) from its reflection spectrum has been demonstrated. By combining the matrix method for calculating the reflection spectrum of a FBG and the adaptive simulated annealing technique, we obtain a new method for the distributed sensing. The numerical simulations show good agreements between the original and the reconstructed strain profiles. (C) 2003 Elsevier B.V. All rights reserved.
