Abstract

Real-time digital holography is used to study the diffusion process in transparent liquid solutions. Holograms of an object diffusively reflecting through an experimental cell containing diffusing solutions are recorded at different time instances. The recording medium is a CCD chip. The holographic interference of the object at two time instances is carried out numerically in a PC and is used to determine the diffusion coefficient. Holographic interferometric fringes can be displayed on a PC monitor in near real time. The software developed for this method determines the diffusion coefficients automatically. The calculated diffusion coefficients obtained with this method matched well with literature values.
