Abstract
In this work is presented a method for observing directly the behavior of t he interface in a liquid-liquid system and in particular the interfacial ce llular convection in the system water-acetic acid-butylacetate. The techniq ue used for visualizing interfacial turbulence is real-time dynamic hologra phic interferometry (HI) in Bi12TiO20 (BTO) crystal in four-wave mixing con figuration. The present method is quicker and simpler than other optical me thods to study interfacial turbulence. (C) 2000 Elsevier Science Ltd. All r ights reserved.
