Abstract: In view of the surface-tension and interfacial tension study experiments the new optical scheme of the radius of curvature determination is proposed. The radius of curvature is determined in the vertice of the sessile drop. The method is based on the observation of the interference patterns in the modified Michelson interferometer.

Keywords: interface tension measurements, drop shape parameters, optical methods, interference pattern.
