WebI'm trying to write a piece of code that calculates a diffraction pattern similar to an X-ray experiment using a FFT. From my knowledge, the diffraction pattern for point particles … WebIn general, an inverse Fourier transform would involve an integral like the forward Fourier transform, but if the object is periodic (like a crystal), it involves just a summation. (As we have seen, diffraction from a crystal cancels out in all directions, except those specified by integer Miller indices.)
