Background removal

Electrons of all energies scattered from the sample form a background to the diffraction pattern, which reduces the contrast of the Kikuchi bands. The background intensity can be removed to improve the visibility of the Kikuchi bands. The background can be measured by scanning the beam over many grains in the sample to average out the diffraction information. The background can be removed by subtraction from, or division into, the original pattern. (Figure 3)
