Electron back-scattered pattern (EBSP) analysis in the scanning electron microscope as a tool for investigating microstructure has been well established. This technique has many advantages over transmission electron microscopy. A drawback of this technique is the angular resolution limit associated with noise in the orientation measurements. This limitation is particularly restricting for the investigation of deformed microstructures where there may be many small misorientations in the microstructure, and where the EBSP pattern quality is generally low, giving a great orientation noise. To aid the interpretation of EBSP data it is necessary to quantify the level of this orientation noise. Orientation noise can be easily determined on perfect single crystal samples, but cannot be determined in the same way on deformed samples. It is expected however that the orientation noise associated with the examination of deformed samples will be worse. Before discussing some possible solutions for the estimation of orientation noise on deformed samples, it is necessary to consider how best we can quantify the orientation noise.
