Particle size analysis using scatter signal magnitude from an interference fringe pattern

An analysis is presented of the relationships between particle size and the signal magnitude obtained by light scattered from a dual scatter laser velocimeter interference fringe pattern. The results of the analysis are used to perform a parametric study for some of the factors that affect the performance of a laser interferometer that is designed to measure velocity and particle size. A comparison of the experimental data with performance predictions confirms the essential validity of the analysis.
