Abstract

A noninvasive phase-shifting laser feedback interference microscope to investigate the evolution of the precursor films ahead of moving contact lines in "dry spreading" of perfectly wetting van der Waals fluids was utilized. The instrument have sufficient resolution and dynamic range to resolve details of both the physics of the inner interfacial region and its interconnection to the outer fluid response. Thus, the observed coupling between these regimes was found to be in good agreement with theoretical predictions and numerical simulation.
