Software support for electron diffraction
Electron diffraction: parallel illumination

There are many software packages available for simulating diffraction patterns. We would like to mention two of them, which are characteristic of two different approaches. Diffraction can be approached either from a geometrical angle, with verification of Bragg conditions, or from a more physical angle, with resolution of the differential equations of electron scattering by a crystal.

• In the first instance, we refer to the Electron Diffraction software (figure 14) developed by Morniroli [16]. The advantage of a geometric approach is that it doesn't require a lot of computing resources. Calculations are fast. The interface is user-friendly and the software is easy to learn. Simulation of the point map consists...
