Off-axis electron holography
============================
.. versionadded:: 0.3.0
The off-axis holography applications (see :ref:`holography app` for the application examples) are realized in
two modules: UDF for off axis electron holography reconstruction and utility function for hologram simulations.
Hologram reconstruction
-----------------------
The reconstruction module contains class for reconstruction of off-axis holograms using Fourier-space method
which implies following processing steps:
* Fast Fourier transform
* Filtering of the sideband in Fourier space and cropping (if applicable)
* Centering of the sideband
* Inverse Fourier transform.
