Abstract: We have calculated the angular distribution of the light intensity in the diffraction pattern arising upon scattering of a laser beam on a suspension of red blood cells in an ektacytometer. We have estimated the diffraction pattern visibility in the region of the first diffraction minimum and the first diffraction maximum as a function of particle size variation. It is shown that in this fragment of the diffraction pattern its visibility decreases already twofold in the case of a standard deviation of the particle size from the average value, equal to 8 %.
