Optical properties of human whole blood: changes due to slow heating

Research output: Chapter in Book/Report/Conference proceedingsChapterpeer-review

Abstract

Changes of coefficients of scattering (μ s), absorption (μ a) and average cosine of scattering (g) depending on shear rate of moving whole blood are described. The most interesting result is observed nonlinear dependence between absorption coefficient and shear rate of moving blood with maximum of μ a at 135 s -1 which is close connected with erythrocytes orientation and deformation in the cuvette. Phenomenon takes place for 488 and 587 nm within blood layer thickness form 100 to 200 μm. Theoretical analysis for angular dependence of coefficient of absorption whole blood from erythrocyte orientation and is presented.
