摘要

Speckle correlometry gives the possibilities to visualize tissue scattering structure analyzing the correlation characteristics of speckle-modulated images. In this work, the inhomogeneous multiple scattering medium with the «dynamic» long inclusions was investigated like a blood vessels in living tissue. The scattering media is 0.28 %weight fraction of gelatin dissolved in water and 100 mg per liter (gL~(-1)) of TiO_2 for optical scattering. The movement of fluid (distilled water) in the cylindrical hole with given radius simulate a blood motion in the vessel. It was shown the possibility to determinate the depth location of dynamic inhomogeneities inside a scattering medium.
