Otú ọ dị, physics nke electron scattering na electron microscope image formation bụ nke a maara nke ọma iji kwe ka simulations ziri ezi nke electron microscope images.As a result of the interaction with a crystalline sample, the electron exit wave right below the sample φe(x,u) as a function of the spatial coordinate x is a superposition of a plane wave and a multitude of diffracted beams with different in plane spatial frequencies u (spatial frequencies correspond to scattering angles, or distances of rays from the optical axis in a plane diffraction).
