Possibility of Measuring of Erythrocyte Size Distribution Parameters by Laser Diffractometry of a Blood Smear

We consider the issues of obtaining information about the distribution of red blood cells in size from the scattering pattern of a laser beam on a wet blood smear. Within this article it is assumed to calculate the first three moments of the size distribution. The analytical model of light diffraction by blood smears was developed, as well as numerical experiments for verification suggested approach were carried out. The possibility of calculating average diameter of erythrocyte, width and asymmetry of size distribution by analyzing the angular distribution of light intensity in the diffraction pattern was shown
