Implementation of Inverse Multiprofile Streak Technique.
Abstract
The inverse multiprofile streak technique is a method that provides information on the detonation wave front's Geometry around the perimeter of an explosive charge. This is achieved by placing multiple slits, in the form of dark and clear horizontal bands, around the perimeter of the charge. The detonation is then observed with a high speed streak camera. The film results yield the time the detonation wave front passes each intersection between the dark and clear bands. The orientation of the detonation wave can be determined from the time of arrival data. This technique was previously published by its developers. Their paper did not discuss the details of the testing or the analysis used. This report details our implementation of the technique and our analysis of multiple tests was made easier by interfacing a motion analyzer with a personal computer. A program listing is included in the appendix. The objective of this report is to make the inverse multiprofile streak technique readily available for use in the development programs. Keywords: Ultra high speed photography; Streak photography; Explosive testing.
