Analysis of laser beam scattering by an ensemble of particles modeling red blood cells in ektacytomter

A. V. Priezzhev, S. Yu. Nikitin, A. E. Lugovtsov


Using a simple theoretical model, we have obtained approximate relations between the characteristics of particles, modeling red blood cells, and the parameters of the diffraction pattern, produced by a laser beam diffracted in the ektacytometer. We have estimated, in particular, the effect of the particles size dispersion on the diffraction pattern visibility. The estimate shows, that relation of light intensities in the first minimum and the first maximum in the diffraction pattern is a parameter, which is rather sensitive to the particles size dispersion.
