Orientation Microscopy and Orientation Mapping

The concepts of orientation microscopy and orientation mapping were introduced in Section 1.2.3. Orientation microscopy refers to the automated measurement and storage of orientations according to a prede ned pattern of coordinates on the sampling plane of the specimen. Once this basic information (orientation plus position) is stored, it can be processed and output in a numbers of ways, which is the topic of this chapter. The pictorial output of these orientations with reference to the sampling coordinates provides an orientation map of the spatial orientation distribution; that is, it derives the “orientation topography.”
