Dear 3DEM Community,

We would like to draw your attention to a Fourier Analyser tool, available at
https://urldefense.com/v3/__https://lbem-status.epfl.ch/ft__;!!Mih3wA!DikAk09fayPbKIP3WjktjK38BsfrZN_VzOVqzBtxYG_9CwGXO5r1UHSPVwwoskd3n7aCsCC4bao5HuDVpHfpCMii2yccifE$ 
with a manual at
https://urldefense.com/v3/__https://lbem-status.epfl.ch/ft/manual.html__;!!Mih3wA!DikAk09fayPbKIP3WjktjK38BsfrZN_VzOVqzBtxYG_9CwGXO5r1UHSPVwwoskd3n7aCsCC4bao5HuDVpHfpCMiiuUGfGaQ$ 

This allows to explore 2D Fourier space. It is a great tool for classroom teaching, since it runs in a webpage and therefore is not limited in computing capacity.
There is an also a set of 10 exercises with explanations available.

Have fun,

Henning.
