Figure 3
Measurement of the azimuth ( ≃ 71.4°) and polar angle (θ ≃ 43.7°) of a lattice-plane trace, highlighted by a bold red line. The dashed red frame indicates the size and position of the backscattered Kikuchi diffraction pattern for = θ = 0 . This initial alignment automatically defines the real position of PC′ in the pattern since it is indicated by the origin (rotation point) of the Hilton net. The experimental BKD pattern comes from magnetite (Fe3O4). |
