The accurate measurement of detonation velocity of high explosives is of fundamental importance in order to improve their design and manufacturing conditions as well as qualifying both vulnerability and aging. CEA LIST, CEA-Gramat and SAFRAN-Herakles are studying the performance of Chirped Fiber Bragg gratings for in situ distributed velocity measurements.
