[Characteristic transient times measured by backscattered laser light in blood suspension flow (author's transl)].
An optical method is proposed for studying rouleaux formation and red blood cells (RBC) orientation. Both relations, first between m, the mean number of RBCs per rouleau and reflectivity, and second between the oriented RBCs fraction and the variation of the isotropic reflectivity are proposed. Our experimental data about aggregation relaxation time and orientation relaxation time are discussed and compared to viscometric results.
