A new method for measuring the diffusivity of liquid binary mixtures using DSPI

A simple and compact digital speckle pattern interferometer is proposed to measure the isothermal diffusion coefficient in transparent mixtures. The diffusion constant is determined directly from the skeletonized video correlogram. An example of diffusion coefficient measurement of a binary liquid mixture demonstrates the usefulness of the method.
