摘要

The dynamics and stability of thin liquid films have fascinated scientists over many decades.Thin film flows are central to numerous areas of engineering,geophysics,and biophysics and occur over a wide range of lengths,velocities,and liquid property scales.In spite of many significant developments in this area,we still lack appropriate quantitative experimental tools with the spatial and temporal resolution necessary for a comprehensive study of film evolution.We propose tackling this problem with a holographic technique that combines quantitative phase imaging with a custom setup designed to form and manipulate bubbles.The results,gathered on a model aqueous polymeric solution,provide unparalleled insight into bubble dynamics through the combination of a full-field thickness estimation,threedimensional imaging,and a fast acquisition time.The unprecedented level of detail offered by the proposed methodology will promote a deeper understanding of the underlying physics of thin film dynamics.
