We demonstrate the use of adaptive simulated annealing (ASA) algorithm for determining the strain profile along a fiber Bragg grating (FBG) from its amplitude reflection spectrum. By combining the ASA algorithm and the matrix method for calculating the reflection spectrum of a FBG, the FBG sensor can be used for the distributed strain sensing. Experiments showed that the strain detection accuracy...
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...
