HoloDark generates quantitative deformation and strain maps over wide fields of view from a pair of dark-field electron holograms using the geometric phase analysis (GPA) technique (see GPA plug-in).
HoloDark is based on the patented technique and routines developed by Martin Hytch.
If you have a high-performance stable STEM, you can get a fully two-dimensional strain map over a similar field view and accuracy using STEM Moiré images (see sMoire plug-in), which is also based on the GPA technique.
