Gazing at crystal balls: Electron backscatter diffraction pattern analysis and cross correlation on the sphere
Ralf Hielscher, Felix Bartel, Thomas Benjamin Britton
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…
