The scattering of coherent light from an evolving system bears the signature of the basic physical phenomenon. Dynamic speckle from blood flow can be used to yield essential information about the underlying process. The properties of these speckle patterns fluctuate depending upon when the image is captured during the process. There is thus a rapid change in the properties of the images including the fractality of the images. The speckle images can be analyzed to extract the parameters of flow using this. In this paper, we report the results of experiments done to study blood flow based on fractality of speckle images. Experiments are conducted for a sample model using a glass capillary and red color pigment solution and an anesthetized rat to confirm the feasibility of the proposed method.
