We have seen (page 126) that the intensity of a Bragg reflection is proportional to | F ( h )| 2 , where F ( h ) is the Fourier transform of the density of scattering matter in the unit cell of a crystal, evaluated at the point h = h a * + k b * + l c * in the ...

The Fast Fourier Transform (FFT) is a family of numerical algorithms which has a large number of uses in many fields of computational science and in particular in signal and image processing. Typically the transformation can be thought of as taking a signal which is a function of time, fo...

We introduce a fast Fourier transform on regular d-dimensional lattices. We investigate properties of congruence class representants, i.e. their ordering, to classify directions and derive a Cooley-Tukey algorithm. Despite the fast Fourier techniques itself, there is also the advantage of this trans...
