Fiber Optic Diagnostics for Scaled Explosion Experiments

Measurements taken with new fiber optic shock wave diagnostics are used to identify plastic and elastic deformation of material under shock compression. This deformation is caused by a point like explosion in a spherical cavity within a containment material and is observed by monitoring cavity wall motion using a fiber tip sensor. Additionally, a new fiber optic loop diagnostic analogous to a Dremin loop is also demonstrated for the first time and the benefits are discussed.
