Abstract
All 16 elements (Xij) of phase matrix (PM) show sensitivity to changes in sizes, and shapes of erythrocite aggregates. The mean size of the aggregates was approximately 200 micrometers . Such aggregates are present in blood under many diseases, such as atherosclerosis, diabetes, etc. Blood erythrocites adhere each other by their plane surfaces to form so-called `coin columns.' PMs of whole blood samples were measured for ills directly after sampling without pre-preparation and for healthy donors. Both the common features of PM and the angular distribution of PM elements are studied for observation angles from 100 to 170 degree(s). To measure elements of phase matrix under single scattering and such a high density, we have been caused to study erythrocytes within a thin layer. Thickness of the layer was 10 micrometers . Single erythrocytes are not deformed within it, but the aggregates oriented normal to the scattering plane. The structure of measured phase matrices was influenced by this fact. Analysis of measured matrices has shown their structure does not differ for samples with extended or weak aggregation.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
