Fibre-optical techniques for measuring various properties of shock waves
conference paper
For the past years we have developed several optical techniques to measure properties of shock waves. The fibre optic probe (FOP) is developed to measure the shock-wave velocity and/or the detonation velocity inside an explosive. The space resolution can be as small as 0.5 mm. Single fibres are used as velocity pins, and as devices to measure the flatness of flyers. Arrays of fibres are used to measure the curvature of a shock or detonation front. Also a Fabry-Perot Velocity Interferometer System is constructed to measure the velocity of the flyer of an electric gun and the particle velocity in a shock wave. It is possible to combine these two measurements to determine simultaneously the flyer velocity that induces a shock wave in a sample and the particle velocity in a window material at the back in a single streak record.
