Basics and demonstrations
- Interference of Waves | Superposition and Interference in light and water waves
- Interferenz bei der Überlagerung von Wellen
- Interference of Light by Dr. Vishal Jain
- The Michelson Interferometer
- Louw Feenstra and his interferometer
- The iridescent colours of soap bubbles
The iridescent colours of soap bubbles not only fascinate young and old, they also open a bridge for our senses to the effects of the nanometre dimension.
The video shows the interference on a thinning soap skin in different spectral ranges. This experiment is part of a presentation that introduces children to the effects of nanotechnology at the Centre for Micro and Nanotechnologies at TU Ilmenau (responsible Dr. Arne Albrecht).
- Length measurements over long distances
... pose a challenge to
- the correct dimensioning of the optics,
- the radiation power and
- the environmental detection.
To the World Interferometry Day, the SIOS shows that one can make measurements over more than 80 m with a small compact interferometer.

Events in Ilmenau
- Live-Action in Ilmenau, 14.04.2021
Am Welttag der Interferometrie zur blauen Stunde, also in der Dämmerung, werden an der Lupe vor dem Ernst-Abbe-Zentrum farbenfrohe Interferenzen zu sehen sein. Die Organisatoren laden Sie hiermit herzlich ein, unsere kleine Show zu genießen, natürlich unter Beachtung der geltenden Regeln!
On the World Interferometry Day at the blue hour, i.e. at dusk, colorful interferences will be seen at the magnifying glass in front of the Ernst Abbe Center. The organizers hereby cordially invite you to enjoy our little show, of course in compliance with the applicable rules!
- Laser harp
Experience Prof. Eberhard Manske with a musical contribution on the laser harp. The head of the Department of Process Measurement and Sensor Technology and co-initiator of the World Interferometry Day is musically active in various genres in his spare time. The combination of laser technology and music reveals itself particularly spectacularly in the laser harp.
- Not entirely serious vision of future applications of interferometry ...
or: we also need a bit more humour in science
