Version 1.1.3  (09/31/2010)

FTL-SE is a program for performing Fourier Transforms, which can be useful in teaching Crystallography, since they are related to Optical Transforms (e.g. laser diffraction patterns). Furthermore one may get a quick hands-on experience with the usefulness of processing images in the frequency domain for certain band filters etc. This software is Freeware and can be distributed freely.

The program includes images, HTML tutorials (English, French) and the PDF article by E.Aubert & C.Lecomte, "Illustrated Fourier transforms for crystallography", J.Appl.Cryst. (2007), 40, 1153-1165.
