WebCherns and Preston first described the contrast of dislocations in LACBED patterns in 1989 [74,75]. They found the simple criterion, called the Cherns–Preston rule, that g · b equals the number of splittings visible at the crossing point of a dislocation line with Burgers vector b and the Bragg line with diffraction vector g = hkl.

The principle is that the incident probe does not focus at the specimen, such that a shadow image of the illuminated region is projected onto the diffraction disc. The spatial resolution of the shadow image is roughly the diameter of the focussed probe.
