Laue zone

Laue zones are defined as the reciprocal lattice planes perpendicular to the direction of the incident beam. The Laue zone containing the origin (reciprocal lattice point corresponding to the incidence point) is called the zeroth-order Laue zone, and Laue zones of the n-th-order counted from the origin to the opposite direction of the incident beam are called the n-th-order Laue zones. The diffraction pattern is considered as the section of the reciprocal lattice points on the Laue zones cut by the Ewald sphere. The reciprocal lattice points belonging to the same Laue zone appear in a circular or an arc form in a diffraction pattern. The radius of the circle or arc is larger for higher-order Laue zones.
