Particulate size measurements using light scattering techniques

Particle size distribution measurements using a small-angle near-forward light scattering (SANFS) arrangement have been found to be a promising technique for applications in combustor environments and advanced power systems. In this paper, characteristics of the light scattering response for this optical arrangement are discussed in detail based on Mie theory calculations. Preliminary data from a bench-scale experiment and a means to improve measurement accuracy are reported.
