Gazing at Crystal Balls โ€“ Electron Backscatter Diffraction Indexing and Cross Correlation on a Sphere

We present spherical analysis of electron backscatter diffraction (EBSD) patterns with two new algorithms: (1) band localisation and band profile analysis using the spherical Radon transform; (2) orientation determination using spherical cross correlation. These new approaches are formally introduced and their accuracies are determined using dynamically simulated patterns. We demonstrate โ€ฆ
