Basics of EBSD

 

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.
