Automatic measurement of particles from holograms taken in the combustion chamber of a rocket motor

Approved for public release; distribution is unlimited / This thesis describes the procedure used for the automatic measurement of particles from hologram taken in
the combustion chamber of a rocket motor while firing. It describes the investigation done on two averaging
techniques used to reduce speckle noise, capturing the image focused on a spinning mylar disk and software
averaging of several image frames. The spinning disk technique proved superior for this application. The
Kolmogorov-Smirnov two-sample test is applied to
different particle samples in order to find an estimate of
the number of particles required to obtain a stable
distribution function. The number of particles is
calculated and given. The last part of this study shows
real particle distributions in the form of frequency
histograms. / http://archive.org/details/automaticmeasure00carr / Major, Canadian Armed Forces
