Abstract

We consider a number of diffusive and transport models of light transmission through whole blood, targeting better understanding of nature of optical transmission pulsations for blood flow modulated by heartbeats. We claim the existence of scattering- associated mechanism rather than the absorption-associated one. Single erythrocytes and their aggregates are considered to be the main centers of scattering in the red- near infrared spectral region. The shape and size of aggregates change in time due to blood flow changes. The corresponding changes of optical transmission are simulated.
