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.
