The method overcomes the restrictions of kinematic orientation determination by EBSD, which is limited to the centrosymmetric Laue-groups connected with Friedel's rule. Different cubic and hexagonal materials (GaN, ZnO) are tested in a quantitative pattern matching approach based on simulations using the dynamical theory of electron diffraction. This procedure results in a distinct assignment of the local orientation in complex materials according to the non-centrosymmetric point group of the crystal structure.en667conference paper
