Abstract
We report a performance comparison of fiber Bragg gratings (FBGs) sensor interrogation using two kinds of wavelength swept lasers. In a wavelength swept laser with a fiber Fabry-Perot tunable filter (FFP-TF), the reflected signal from the FBGs in temporal domain has a nonlinear response with respect to the sinusoidal modulation signal. The output of the time delay for the strained FBGs sensor array in the wavelength swept laser with FFP-TF has different slope coefficient for each FBGs, while the reflected output of the strained FBGs in the wavelength swept laser with polygon scanning filter has same slope coefficient for each FBGs.
