Measurement of an Explosively Driven Hemispherical Shell Using 96 Points of Optical Velocimetry
ORAL
Abstract
We report the measurement of the surface motion of a hemispherical copper shell driven by high explosives. This measurement was made using four 32 channel~multiplexed photonic Doppler velocimetry (PDV) systems, in combination with a novel compound optical probe. Clearly visible are detailed features of the motion of the shell over time, enhanced by spatial correlation. Significant non-normal motion is apparent, and challenges in measuring such a geometry are discussed.
