3D tomography

[heidemeissner]

To the best of our knowledge, tomographical ptychography is always reconstructed by

• reconstructing the 2D measurements acquired for the same angle
• the fusing the results by a filtered backprojection

Wolfgang had the idea of trying a real 3D reconstruction by inverting all data together, i.e. using polar coordinate shifts instead of cartesian ones.

From a mathematical point of view this seems to be feasible. The benefit would be less required data points and thus less artefacts. The drawback is the amount of data which is now considerably increased by magnitudes which is needed for each single iteration now putting through all data. This is the task for WP3 when the algorithm is adapted => WP1
