Abstract
A laser speckle technique is proposed for the study of diffusion in tr ansparent liquid mixtures. The diffusion constants may be deduced by a simple manipulation of the speckle patterns recorded during the diffu sion process. The proposed method, checked with the LiBr-water system, gives reasonable agreement with existing data.
