Particle Diagnostics Using Mie Scattering and Image Intensification Techniques.

Abstract

The visualization of a particulate-laden flow field immersed within a hypersonic flow has been achieved using Mie scattering. The visualization technique employed the injection of a modulated laser beam which was expanded to provide observation of a broad spatial region of the particulate plume. The Mie scattered radiation was detected by an image intensifier tube, the output of which was detected by a fast-framing camera. A description is provided of this system, the analysis of the data, and the results.
