Paper Abstract

The article presents the influence of the length of fiber Bragg grating with linear changeable period on processing accuracy of impulsive excitations acting along the longitudinal fiber axis. Using transfer matrix method the power reflectivity spectrums caused by impulsive strains are obtained. On this basis, assuming that grating's output signal is of centroidal frequency, the mean square error was evaluated as a function of the ratio of the length of the grating to the length of impulse, for different shapes of impulsive strains.
