The classical dynamical theory of X‐ray diffraction is expanded to the special case of transversely restricted wavefronts of the incident and reflected waves. This approach allows one to simulate the two‐dimensional coherently scattered intensity distribution centred around a particular reciprocal lattice vector in the so‐called triple‐crystal diffraction scheme. The effect of the diffractometer's instrumental function on X‐ray diffraction data was studied.
