Abstract

It is widely known that both the speckle pattern generated by the axial movement of a rigid diffuser surface, as well as the speckle pattern registered with low resolution, present blur-up. In the first case a blur-up criterion was proposed and applied to the study of vibrations. The statistical and optical properties of dynamic diffusers are also well modeled and well known. This paper proposes a numerical criterion to determine the blur-up of the speckle pattern resulting from superposition patterns generated by dynamic diffusers. Its application is illustrated in the analysis of the Brownian motion of colloidal particles.
