Abstract

The correlation diffusion equation is used to calculate laser Doppler spectra for semi-infinite homogeneous and semi- infinite two-layered turbid media at different distances from the incident source. The influence of the optical coefficients on the laser Doppler spectra is show using the semi-infinite geometry. The two-layered geometry is applied to investigate the influence of the first layer (for example: the layers above the muscle in the extremities) and second layer (for example the muscle) on laser Doppler measurements. The possibility to extract the root-mean-square velocity of the blood cells in the second layer (muscle) using a semi-infinite homogeneous model is discussed.
