Abstract
Abstract
We present dynamic optical strain measurements on a metallic cylinder asymmetrically loaded by explosives bands using 24 fiber Bragg gratings distributed along three fibers. The 100 MHz dispersive spectrometer reveals resonances without any electromagnetic perturbations compared to slower electrical strain gauges.
