Paper Abstract

The experimental research and theoretical modeling of the erythrocyte refractive index have been carried out. It has been proposed the model of the erythrocyte refractive index determination by means of two wavelengths (0,63 and 0,53 micron). It has been shown that the power density of laser radiation has an influence on erythrocyte deformability and hence on changing of the erythrocyte refractive index. The value of the obtained refractive index by means of two wavelengths method is in a good agreement with the haemoglobin concentration in explored sample of blood.
