Nanovisc is a tool for extracting the viscosity of thin films from overhead videos. Users input
certain key properties of their system, including the refractive indices and initial thickness of
components in the optical path, the properties of the illumination, as well as the pressure
applied to the material. There is one layer of interest in the system: a thin film, whose thickness
is changing under applied pressure. The tool simulates the expected intensities at a given thin
film thickness and maps the experimental intensities, from user video, onto the simulated
intensities in order to extract thickness as a function of time. The time evolution of thickness and
the user-supplied pressure profile are used to determine the viscosity.
