Interferometric Particle Sizing
Abstract
The theory and experimental conditions are summarized under which single, spherical particles in the size range of a few micrometers and larger may be accurately sized using the observed fringe visibility in a crossed-beam laser velocimeter. Scalar diffraction theory and experimental data are presented to show how the size information in the forward scattered light is dependent on the collection optics geometry, including the size and shape of source beam stops. The scattered light signal waveform is analyzed in both the time and frequency domains, and electronic instrumentation is outlined for rapid acquisition of size data. (Author)
