As band positions are characteristic not only for crystal orientations but also phases themselves, it is important to correctly predict the most intense bands. This is an important support for correct phase identification via EBSD. While conventional intensity prediction using kinematic theory simulation works reasonably well for simple structures, like most technical phases are, the situation changes entirely, when looking at more complicated structures. Here kinematic theory fails in many cases, providing wrong intensities.

The solution is to use dynamic theory simulation. This has become a viable option now, as computer performance is ever increasing, supporting complex calculations in shorter time. Bruker has therefore released a pattern simulation software based on dynamic theory for its QUANTAX EBSD system. This software provides the desired reliable intensity predictions for complex phases and much more.

In summary, Bruker's dynamic simulation software offers following possible applications, as listed below.

Fundamental understanding of EBSD pattern formation, e.g.

• reliable prediction of information depth
• influence of energy distribution

Extraction of real band intensities for the

• indexing of crystallographically more complex phases
• prediction of pseudo-symmetries relevant in practice

Generation of reference patterns for

• phase verification and identification
• point group determination (e.g. polar direction) 
• lattice strain approximation.
