Light diffraction from shear ordered colloidal dispersions is discussed in terms of the scattering power distribution I(l) along Bragg rods of hexagonal layers. For a charge stabilized dispersion the angle dependence of the light scattering intensity is used to determine I(l), from which conclusions on the mutual registration of the layers, the stacking order, and the kinetics of crystallization can be drawn. For the system under study a structural transition from random close-packed hexagonal layers to faulted twinned fcc is identified.
