An Investigation of Particle Size Distribution Using Laser Holography of Burning Solid Propellant

Abstract

A test area was modified to allow holographic recordings to be made of burning solid propellant samples as contained in a pressurized window bomb. A holographic reconstruction area was also established. An attempt was made to develop a semi-automated holographic data retrieval (HDR) system using existing AFRPL hardware. The purpose of the HDR system was to retrieve particle size and positions information in a timely manner from holographic reconstructions of the propellant combustion. Experiments with the HDR system revealed serious deficiencies in the areas of resolution and particle recognition. Since a primary goal of the program was to establish particle distribution correlations from holographically derived particle information, the present program has been inactivated pending the development and acquisition of an improved HDR system.
