Abstract: The scattering of coherent light from an evolving system bears the signature of the basic physical phenomenon. The characteristic 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 pulsatile flow with speckle images.

 

Keywords: Scattering, Speckle, Statistical optics, Turbid media.
