Abstract

Interference methods allow researchers to obtain the information about normal displacements of a phase surface with high resolution and in real time. This opportunity was realized to observe time changes of the height of evaporating drop accurate to a fraction of the wavelength of visible light. We consider the possibilities of studying processes on a drop surface, that accompany the evaporation and are small-scale in terms of space and time.
