Using computer image simulations based upon the propagation–interpolation algorithm for solving the Howie–Basinski equations, an investigation was made of the relationship between the actual and the ‘observed’ size of small loops, the part played by many-beam dynamical diffraction effects, and limitations of electron microscope imaging in identifying the structure of small defects. The link between real-space imaging and diffuse scattering by small dislocation loops was also considered.
