Dataset Open Access
Electron diffraction patterns taken with a conical illumination (electron Bessel beams) and can be used to measure strain.
The experimental diffraction patterns, in DM3 format, are included in the file experimental_data.7z while FEM strain simulations for the same sample are in the file reference_strain_experimental.csv
Simulated diffraction patterns are included in the file simulated_patterns.7z while the strain in the model used is in the file reference_strain_simulated_patterns.csv
The two python scripts attached allow the extraction of the strain, and rely on the code published at:
