Abstract : Single and multiple fringe interferograms have been in use in recent years to obtain gas and electron distributions about an exploding wire. Until recently not much quantitative evidence has been obtained about the flow of the metal vapor produced by exploding wires. The purpose of this paper is to establish some geometrical techniques and mathematical relations upon which subsequent analyses of this metal vapor flow, seen in the existing interferograms, may be based. This paper offers certain flow hypotheses, shows the resulting fringe contours for both the single and multiple fringe cases, and compares these fringe contours with some interferograms obtained experimentally.
