I recently came across an excellent phase unwrapping function in scikit-image https://scikit-image.org/docs/stable/auto_examples/filters/plot_phase_unwrap.html
This would have been very useful during my PhD. I did work with digital holographic microscopy, but didn't have a robust way to go from interference patterns to images of the phase. The difficulty with phase unwrapping was one of the main stumbling blocks.
The scipy function is based on a 2002 paper, https://opg.optica.org/ao/abstract.cfm?uri=ao-41-35-7437 , but I wasn't aware of it at the time (2010-2015).
