Monitoring the thinning dynamics of soap films by phase shift interferometry. The case of perfluoropolyether surfactants.

Abstract

An interferometric method to monitor the thinning process of vertical soap films from a water solution of surfactant materials is reported. Raw data maps of optical path difference introduced by the film are obtained by conventional phase shift interferometry. Off-line re-processing of such raw data taking into account the layered structure of soap films… (More)
