Introduction to Basic Crystallography - Zones in the EBSP
• In an Electron Backscatter Diffraction Pattern (EBSP), the intersection of Kikuchi bands correspond to 'Zones Axes' in the crystal
These can be 'indexed' and displayed

Introduction to Basic Crystallography - Indexing
• Indexing an (EBSP) refers to the recognition and labelling of bands and zones in the pattern, which relate to specific planes and directions in the crystal.

Introduction to Basic Crystallography - Euler Angles
• Euler Angles are the three rotations about the main crystal axes
• Euler angles are one possible means of describing a crystal orientation

Introduction to Basic Crystallography - Euler Space
• Euler Space was popularized for macro-texture investigations as the 'Orientation Distribution Function' (ODF).
• ODFs are an established method for interpreting the results from x-ray diffraction

Introduction to Basic Crystallography - The Orientation Matrix
• The orientation matrix describes the absolute orientation of the crystal with respect to the
sample axes.

Introduction to Basic Crystallography - Ideal Orientation Nomenclature
• In this example the orientation of the crystal shown can be written as: {100}<110>

Introduction to Basic Crystallography - Misorientation
• Misorientation is the expression of the orientation of one crystal with respect to another crystal.
