ProSPyX: software for post-processing images of X-ray ptychography with spectral capabilities

Area of Science:

• Coherent X-ray diffraction imaging
• Materials science
• Spectroscopy

Background:

• X-ray ptychography reconstructs sample properties from diffraction patterns.
• Spectral information can be obtained by varying X-ray energy.
• Current methods require complex post-processing for spectral data.

Purpose of the Study:

• Introduce ProSPyX, a Python package for spectral ptychography data analysis.
• Simplify the extraction and analysis of spectral information from ptychographic datasets.
• Facilitate integration with existing X-ray absorption spectroscopy workflows.

Main Methods:

• Developed ProSPyX using Python and PyQt5 for a graphical user interface.
• Implemented algorithms for extracting absorption and phase spectra.
• Ensured output compatibility with standard spectroscopy data analysis tools.

Main Results:

• ProSPyX successfully processes spectral ptychography datasets.
• The software extracts absorption and phase spectral information.
• Generated spectra are saved in formats compatible with other analysis software.

Conclusions:

• ProSPyX streamlines spectral ptychography data analysis.
• The software enhances the utility of X-ray ptychography for materials characterization.
• ProSPyX facilitates the integration of ptychographic spectral data into broader spectroscopic analyses.
