Abstract: A simulation method for evaluating dynamic strain distribution along a uniform Fiber Bragg Grating (FBG) using its reflection spectrum is presented in this paper. This method is valid for simulating both uniform and non-uniform strain distributions along the FBG under various dynamic conditions. The reflection spectrum from the FBG, subjected to different strain profiles, is simulated based on the Transfer matrix (T-matrix) approach. Three strain profiles, such as a uniform strain, a linear strain gradient and a quadratic strain field, are selected to demonstrate the viability of the proposed method. The importance of the dynamic simulation of the reflection spectrum on the filter design in a FBG dynamic strain sensing system is highlighted.
