Flash X-Ray with Image Enhancement Applied to Combustion Events.

Abstract

Flow visualization of interior ballistic processes by use of x-ray has placed more stringent requirements on flash x-ray techniques. The problem of improving radiographic contrast of propellants in x-ray transparent chambers has been studied by devising techniques for evaluating, measuring and reducing the effects of scattering from both the test object and structures in the test area. X-ray film and processing is reviewed and techniques for evaluating and calibrating these are outlined. Finally, after x-ray techniques have been optimized, the application of image enhancement processing which can improve image quality is described. This technique has been applied to x-ray studies for the combustion of Very High Burning Rate (VHBR) propellants and stick propellant charges.. Originator supplied keywords include: Image enhacement; Compton effect; Films; Developers; Scattering; Pseudo color; Screen; Collimator.
