With ever increasing demands for more detailed and accurate data in the energetics community, it is of significant importance to utilize new techniques to expand the testing capabilities to meet the demands imposed by program requirements and modeling and simulation needs. In this series of experiments, fiber Bragg gratings FBG were used as a detonation wave position sensor. Testing allowed for verification of system functionality, establishment of best practices, and the creation of analytical techniques to properly transform the captured voltage data to the corresponding distance data. These experiments yielded important pretest procedures and discovery of sources of noises in the system. Additionally, edge effects of the FBG spectrum response were accounted for. Verification of FBG system performance was achieved through comparison of the FBG methodology against a piezoelectric pin array to estimate system accuracy.
