FBG Bandwidth Impact on Dual-Comb Interrogation for High Fidelity Strain Sensing_dataset

This dataset contains processed experimental data used in the study of bandwidth-adaptive dual optical frequency comb (DOFC) interrogation of Fiber Bragg Gratings (FBGs) for high-resolution static strain sensing. The work investigates the robustness of a single EI-GSL-based DOFC interrogation platform combined with an inverted Gaussian fitting (IGF) algorithm when applied to FBGs with different spectral bandwidths.The dataset provides the strain–wavelength shift data used to extract calibration slopes, fitting residuals, linearity metrics, and effective strain resolution for both a DOFC-based interrogator and a commercial swept-laser interrogator.
