Abstract

The backscattered intensity from low-intensity laser illumination of the skin in the area of vascular plexus is investigated in vivo. The exposure of blood to low power laser light in the absorption range of haemoglobin leads to increasing intensity of the backscattered light. Theoretical evaluation using an existing optical model of erythrocyte aggregation has suggests that the fragmentation of erythrocyte aggregates is the most probable mechanism leading to the enhanced backscattering.
