Application of high-resolution optical technique to shaped-charge jet formation
A high-resolution, multi-frame, image-converter camera using laser illumination has been developed by the Lawrence Livermore National Laboratory and is being used to observe the liner implosion and jet formation process in shaped charges. The combination of a short 15-ns exposure time and monochromatic laser illumination provides clear, sharp images of the linear collapse and jet formation process unobscured by luminous air shocks or motion blur. The camera as currently configured can take eight independent frames, or four pairs of stereo images. A ruby laser system provides the multiple-pulse illumination source. In stereo images of a copper-lined shaped charge, the liner deformation, including tiny imperfections, and the jet formation processes are clearly revealed. Grid lines placed on the surface of the liner remain intact and can be used for comparison with code calculations. 18 refs.
