Light scattering simulation and measurement of monodisperse spheroids using a phase Doppler anemometer

Mathematical tools are provided for the computation of the scattered field produced by non-spherical particles moving through the measurement volume o f a phase Doppler anemometer. The phase distribution of a spheroid with ran dom orientation is computed by using the rigorous extended boundary conditi on method and the ray theory. In a phase Doppler experiment the spheroid pa rameters are obtained by fitting the measured phase distribution with the s imulated phase distribution. The numerical simulations are supported by exp erimental results on monodisperse spheroids.
