Abstract

A simple procedure, using holographic interferometry, for measuring diffusion in transparent liquids is presented. A Mach-Zehnder interferometer and A CCD linear array are used to record the moving fringes, and the data is processed automatically on a micro computer. The diffusion constant is determined from the velocity of the fringes which are observed in real time. Results of measurements on NaCl solutions demonstrate the usefulness of this technique.
