1. © Oxford Instruments Analytical Limited 2001 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

2. © Oxford Instruments Analytical Limited 2001 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.

3. © Oxford Instruments Analytical Limited 2001 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

4. © Oxford Instruments Analytical Limited 2001 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

5. © Oxford Instruments Analytical Limited 2001 Introduction to Basic Crystallography - The Orientation Matrix The orientation matrix describes the absolute orientation of the crystal with respect to the sample axes.

6. © Oxford Instruments Analytical Limited 2001 Introduction to Basic Crystallography - Ideal Orientation Nomenclature In this example the orientation of the crystal shown can be written as: {100}

7. © Oxford Instruments Analytical Limited 2001 Introduction to Basic Crystallography - Misorientation Misorientation is the expression of the orientation of one crystal with respect to another crystal.
