Abstract: OSDR techniques for spatial characterization of fiber Bragg gratings based on local phase induction by IR or UV radiation have been developed. Both radiation types provide longitudinally and cross-sectionally uniform fiber excitation, high spatial resolution and good sensitivity of measurements.
