Both EDS and EBSD chemical, orientation, and phase mapping are standard techniques that are routinely applied on many materials. When the sample is capable of producing high EDS count rates or high quality EBSD patterns, this type of analysis is straightforward. But when the input data quality is not good , which may happen due to a variety of reasons, the mapping quality will be poor and time consuming. New patented averaging functions have been implemented in the EDAX TEAM software to ensure optimum data quality while minimising loss of detail in your map data. In EDS mode, live phase maps may be constructed using advanced binning with neighbour spectra to improve the element detection and phase identification. In EBSD mode the maps recorded on a hexagonal scan grid may be reprocessed off-line using recorded EBSD patterns with NPAR. This stands for neighbour pattern averaging and reindexing. NPAR takes the pattern at any point in the EBSD map point and then considers the 6 patterns in the hexagon around it. These original 7 patterns are put together and averaged onto the single pattern in the middle which gets indexed.
