Incoherent summation

WebConventional x-ray diffraction has historically been done under conditions such that the measured signal consists of an incoherent addition of scattering which is coherent only on a length scale determined by the properties of the beam. The result of the incoherent summation is a statistical averaging over the whole illuminated volume of the sample, … WebApr 23, 2024 · The coherent sum does not behave in the same way as the incoherent sum.
