FTL-SE 1.2

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.
