Measurement of High-Speed Deformations Using Fiber Bragg Gratings

The application of fiber-optic Bragg gratings in systems of high-speed deformation of materials by the method of magneto-pulse loading is considered. The description of an experimental setup for the formation of pulsed mechanical load and high-speed deformation registration system is presented, as well as the waveforms of the received signals. The results of the evaluation of the strength of the pulsed mechanical action on the Bragg grating and the propagation velocity of the wave of elongation and compression of the optical fiber are provided.
