This submission contains Python code to evaluate interferograms of evaporating liquid films and sample data. It mainly consists of a module for preprocessing, a module to analyze the fringe pattern of the interferograms and a phase-unwrapping module. All is accessible from a graphical user interface and a separate Python script, which focuses on the sequential evaluation of multiple interferograms and includes the calculation of a concentration distribution above evaporating rectangular liquid films.

Please refer to the PhD thesis for a discussion of the implemented algorithms and check 'README.txt' for installation instructions.
