Paper Abstract

When an optically rough surface illuminated by a laser evolves in time the scattered light gives rise to a dynamic speckle pattern and its variation depends on the activity of the sample. Biological samples show this behavior but it also can be observed is some other dynamic processes such as drying of paint, corrosion, heat exchange, blood flow, vibrations, etc. In this work we present a dynamic speckle phenomenon that occurs in the development of foams. The experimental results show the time evolution of the samples and offer a potential applicability of this measurement technique to the assessment of this type of processes.
