Abstract

We describe a holographic system that measures the size distribution of particles ejected from a shocked lead surface at speeds up to 2.8 mm/µs. Observed diameters range from 3μm to 50 μm. The three-dimensional distribution of the particles permits inferences about the uniformity of their distribution and velocity. Comparison of the holographic results for the mass with those obtained using a momentum transfer technique show general agreement but indicate that further refinement of both techniques may be necessary.
