The concert on the laser harp marks the end of the World Day of Interferometry at the Ernst Abbe Centre
The concert on the laser harp marks the end of the World Day of Interferometry at the Ernst Abbe Centre On Wednesday, April 19, 2023, the TU Ilmenau will celebrate for the third time the World Interferometry Day to commemorate the groundbreaking development of the interferometer - a technology that makes it possible to measure the smallest quantities and effects with high precision on the basis of light. To mark the occasion, an international scientific symposium will also be held in the Faraday Lecture Hall as early as April 17. The invention of the interferometer by Albert Abraham Michelson over 140 years ago has become synonymous with high-precision measurement technology based on light. Light waves with the unimaginably small wavelength of a few hundred nanometers "interfere" with each other, i.e. they superimpose in a similar way to water waves. This interference allows the smallest movements to be detected and measured with the greatest accuracy. Pushing this technology to its limits and challenging it to ever new heights - that is the goal of modern precision metrology, a field in which Institute for Process Measurement and Sensor Technology of the TU Ilmenau has been a world leader for many years and works closely with experts from science and industry. Together with the managing director of Ilmenau-based SIOS Meßtechnik GmbH Dr. Denis Dontsov, the institute's director, Professor Eberhard Manske, initiated the World Interferometry Day and organized it for the first time in 2021.
