Riassunto:  A model for the optical path difference introduced by a soap bubble in transmission is described. The model is then used with interferometric data to solve for the fringe order, and to define a procedure to extract the global film thickness in presence of turbulence flows occurring during the drainage process due to gravity. Experimental results on soap bubbles examined in single-pass phase-shift interferometry are presented. (C) 2013 Optical Society of America

Ulteriori informazioni:  This work was performed under the auspices of the Italian Space Agency (ASI), within the project Liquid Film Tensiometer (LIFT). LIFT is an interferometry-based experiment designed to produce, measure and control very thin water bubbles in a fluid matrix in a microgravity environment. Its scope is to study the mechanisms to create and control emulsions and foams with a view to several application domains (chemistry, food, pharmacology, biomedics, and more). LIFT is expected to be flown on the International Space Station. The authors thank the Italian Space Agency for kind permission to publish this work. We are also grateful to C.M.C. Gambi for valuable comments and discussions on the subject of liquid films, and to S. Acciai and M. D\'Uva for fabricating mechanical parts used in this study.
