Make LEED into FFT
Inverse FFT of LEED


Image SXM
Converts a low-energy electron diffraction (LEED) image into an FFT and then applies an Inverse FFT operation. The LUT of the LEED image will be inverted if necessary.

Notes on Inverse FFTs of LEED patterns:
  • For best results, the LEED pattern should be of high contrast and centred in a large image window.
  • If the LEED pattern is not positioned symmetrically, the IFFT will have bands across the image.
  • If the LEED spots are not sharp, the IFFT will have high contrast only in the central region.
