Abstract

A method to measure diffusion coefficient of transparent liquid solutions using digital holographic inteferometry is described. Holograms of a diffusively reflecting object through the experimental cell containing the diffusing solutions are recorded at different time instances. The recording medium is a CCD chip. The holographic interference of the object at two instances of time is numerically carried out in a PC and is used to determine the diffusion coefficient. Holographic interference fringes can be displayed on a PC monitor. The diffusion coefficients calculated using this method matched very well with literature values.
