Abstract

For understanding the interaction between projectiles and target structures at impact velocities up to 2000 m/s and higher, a fast-multi-flash X-ray system is needed to look through materials. For that reason a fast optical diagnostic system was developed which is equipped with a multi-flash X-ray system, a fast decay scintillator screen and a fast gating intensified multi-frame CCD camera. The already low parallax caused by the compact annular installed RXanodes was eliminated by mathematical affine transformation. A first basic version of an image processing and analysing software was developed to eliminate the already low parallax, to improve the image quality, detect fragments and debris, as well as calculating the object velocity. This high-speed diagnostic system was used for ballistic testing to investigate the ballistic performance of composite body armour, ballistic helmets and laminated armour.
