We develop and validate a Modified Beer-Lambert law for blood flow based on diffuse
correlation spectroscopy (DCS) measurements. The new formulation enables blood flow
monitoring from temporal intensity autocorrelation function data taken at single or multiple
delay-times. Consequentially, the speed of the optical blood flow measurement can be
substantially increased. The scheme facilitates blood flow monitoring of highly scattering
tissues in geometries wherein light propagation is diffusive or non-diffusive, and it is …
