| Abstract Scope |
Forward model based indexing of EBSD and TKD patterns provides superior robustness, improved orientation precision, and can resolve common indexing challenges including pseudo-symmetry, non-centrosymmetric point groups (polarity), and overlap patterns. Forward model techniques are more computationally expensive than traditional band detection based indexing techniques, limiting more widespread adoption. New GPU implementations of spherical harmonic indexing and real space orientation refinement both achieve speeds of thousands of patterns per second on modest hardware. An overview of the underlying theory will be presented with example applications. |
