Light deflection and convection in diffusion experiments using holographic interferometry
(2001) In Journal of Physics D: Applied Physics 34(20). p.3088-3096- Abstract
- A study of the effect of light deflection during diffusion studies of ethanol into agarose gel using holographic laser interferometry is presented. Furthermore it also demonstrates how a diffusive flux could give rise to a convective flux in holographic laser interferometry experiments. The convective and diffusive mass transfer is also theoretically compared in both a liquid phase and a gel phase for the ethanol-agarose system used. The current study shows that errors due to light deflection in holographic laser interferometry are extremely small and can be neglected. It also shows the importance of designing the diffusion experiments to avoid natural convection. In gels the convective flow is cancelled by the friction forces between the... (More)

However, in the liquid phase the natural convection could occur even though the density differences in the phase are small. (Less)
