Refractometric measurements of diffusion process: background oriented schlieren method and holographic interferometry with nonstationary reference wave

We suggest yet another illustration of the method of digital image correlation in the Background Oriented Schlieren scheme in application to the process of diffusion of two liquids. Using the method, we realize a dependence of the coefficient of diffusion on concentration and estimate it numerically.
