Fast Re-indexing with up to 54,000 points/s

The EBSD software is capable of re-indexing measurements in incredibly short time. The employed procedure is more than an order of magnitude faster than a completely new measurement. Single phase materials can be re-indexed with around 54,000 points/s. The advantage of re-indexing is that measurements can be re-analyzed when not all phases have been known initially. Even if no phase at all is known, the detected band positions can be used to recalibrate the system later and use the fast re-indexing afterwards for a successive analysis of the microstructure. This works even better if EDS information can be used for further phase discrimination.
