Fourier Transform Lab Student Edition is an advanced application designed for performing Fourier transformations, 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.

FEATURES:

Forward & Inverse Fourier Transform
Low-Pass Filter
High-Pass Filter
Custom-Mask Filter (for removing Fourier peaks)
Image Histograms, Images may be dragged
Swap Phase Sets
Randomize / Discard FT Phases
Randomize / Discard FT Magnitudes
Easy Image Import (Load, Paste, Drag-Drop)
Basic Image Drawing Function (Freehand & Lattice)
Basic Scripting Functions
Extensive HTML Tutorial (Aubert, Lecomte)
