Cartoons showing the Laue diffraction method
These animations demonstrate the use of Laue diffraction in recording diffraction data. The 2D model is more pedagogic in nature, while the 3D model demonstrates how the classical patterns associated with Laue diffraction are produced. The 3D pattern was generated by using an upper k-value of 1 Å-1 and a lower of 0.25 Å-1, and a unit cell size of 40 Å.
By applying a high-pass filter to the detector, overlapping Bragg peaks from families m(hkl) can be distinguished from one another, thereby overcoming the classical “overlap problem” associated with Laue diffraction. These are shown in the last two animations, one with a rotating crystal, the other stationary.
