Abstract

A modification of the Mach-Zehnder interferometer is described which permits streak interferometry of transient axisymmetric flows. Examples are shown of interferograms taken of flows produced by exploding fine metallic wires. Prominent features of the interferograms include (1) clearly defined shock waves, (2) a narrow, transparent, flow region behind the strong shock where fringes may be seen, (3) an opaque region presumed to be caused by the dispersed metal, and (4) luminous regions associated with the second shock wave and electronic excitation of the material near the axis of symmetry.
