between decorrelation time (τ c) and blood flow velocity (V), ie 1/τ c= α V. Using a modified
microcirculation imager (integrated sidestream dark field-laser speckle contrast imaging
[SDF-LSCI]), we experimentally investigate on the influence of the optical properties of
scatterers on α in vitro and in vivo. We found a good agreement to theoretical predictions
within certain limits for scatterer size and multiple scattering. We present a practical model …
