Show affiliationsDynamic speckle or biospeckle is a phenomenon generated by laser light scattering in biological tissues and it is also present in some industrial processes where the surfaces exhibit some kind of activity. In this work we present some results of a numerical model to describe the time history of a dynamic speckle pattern considering very simplified situations. In this case we simulated only the movement of the scatterers, and the obtained results are in agreement with some of the expected from the theory and qualitatively with the experimental results outlined in previous works. Also, we tested the first order statistics of the spatial speckle, the Briers contrast of the time varying part and the moment of inertia of the co-occurrence matrix.
