Summary
-
When an electron beam is incident on a tilted crystalline sample, electron
backscatter diffraction patterns are formed on a suitably placed phosphor
screen.
-
The
diffraction pattern consists of a set of Kikuchi bands which are
characteristic of the sample crystal structure and orientation.
-
The
centre line of each Kikuchi band corresponds to the intersection with the
phosphor screen of the diffracting plane responsible for the band.
-
The
position of the Kikuchi bands can be found automatically with the Hough
transform and used to calculate the crystal orientation of the sample region
that formed the pattern.
