Abstract

The intensity of light backscattered when low-power laser radiation is incident on the skin is investigated under in vivo conditions. The exposure of blood to low-power laser light in the absorption range of haemoglobin leads an increased intensity of the backscattered light. The theoretical calculation using the existing optical model of erythrocyte aggregation has suggest that the fragmentation of erythrocyte aggregates is it most probable mechanism leading to the enhanced backscattering.
