Python3.6 package for processing fringe patterns.
Fringes patterns are a kind of special images obtained, for example, from optical interferometry. These images have a cosine model and can be seeing as two-dimensional cosine signals. When processing fringe patterns, the objective is obtain the modulating phase.
The idea of this package is to offer methods and operations to process fringe pattern images.
- psi has methods and utilities used to demodulate a sequence of phase-shifting fringe patterns.
