For the last 20 years synchrotron sources have produced brighter and more coherent X-ray beams. This has allowed the development of Coherent X-ray Imaging techniques which yield a resolution which is neither limited by the X-ray beam size, nor by the pixel size on the detector.
In this presentation, after introducing the different techniques, I will present the PyNX software currently developed at ESRF (http://ftp.esrf.fr/pub/scisoft/PyNX/doc/), which uses Graphical Processing Units (GPU) to provide 1 to 2 orders of magnitude acceleration in data analysis throughput. I will show:
- the tools already available with the choices in algorithms
- how the python library can be easily extended to new algorithms using an Operator-based approach (without any knowledge in GPU programming)
Examples will include Coherent Diffraction Imaging (in the small-angle and Bragg regimes), Ptychography (near field and far field, small angle and Bragg).
