O (Fig. 104) traverses thecrystal at 0, the undeviated beam striking the photographicplate ZD at Z. Let 08 be a zone-axis ; the rays reflectedin the family of planes which pass through this zone-axislie on a circular cone, of which OS is the axis and OZ andOP are two generators. This cone cuts the… … Fig 104 —Geometrical conetruction to explain stereograpliic projection ofLaue spots. Thus, if we consider the Laue pattern which is formedon the surface of the sphere ZBA, and then project thispattern on the plane ZD from the pole A, we shall havea new projection in which the ellipse with ZP as…
