Measurements of Diffusion Coefficients in Liquids using Holographic Interferometry

Abstract

With the advent of holography, traditional interferometric methods, such as Mach-Zehnder, have been replaced by holographic interferometric techniques. A distinct advantage of the holographic method is that it provides the ability to compare wave fronts that are separated temporally, as well as spatially. This paper describes the application of the technique to measurements of mass and heat transport in transparent liquid mixtures.
