- Аннотация: Ektacytometry is a fast diagnostic technique, which is based on the illumination of a dilute suspension of erythrocytes moving in the shear flow within the thin gap of a rotational couvette with a laser beam. Small angle light scattering results in a diffraction pattern (DP) containing valuable clinical information about the microrheologic properties of the cells. A number of DP-processing techniques were proposed for obtaining the sizes and shapes of the particles. Almost all of them rely on the assumption that a random mixture of two different sets of particles cannot generate the same DP. However, in practice it could happen that the same DPs correspond to two different ensembles of the particles (for instance, because of the orientation of the particles, etc.). In such a case the particle size distribution cannot be reconstructed basing on data obtained from the measured DP. The aim of this work is to examine the situations when the particle ensemble is unique for a given DP. This is the so-called uniqueness problem.
