Paper Abstract

In this paper, experimental results are presented of using a small pulsed YAG laser to ignite detonating powder to produce the temperature field of transient combustion, and of using a method of serial pulsed laser interferometry to obtain time series interferograms of the combustion process of detonating powder. By means of a computer, a detecting method of fringes thinning is used to thin the fringes of time series interferograms, and fringe displacements are read automatically. The transient temperature distribution of the combustion field of detonating powder and the changes of temperature with time in the combustion process are calculated quantitatively.
