Demonstration of a compact optical resonator-based displacement sensing technique with sub-femtometer precision
Shreevathsa Chalathadka Subrahmanya, Jonathan Joseph Carter, Oliver Gerberding
We demonstrate sub-femtometer displacement-sensing results achieved with a compact optical resonator-based laser interferometry technique called heterodyne cavity-tracking, intende…
Distributed Acoustic Fiber Sensing for Research Campuses and Large Scientific Infrastructures -- The Hamburg WAVE proto-network
Oliver Bölt, Luigia Cristiano, Sandy Croatto +17
Here, we demonstrate and investigate how Distributed Acoustic Sensing (DAS) can be utilized on research campuses and in large scientific infrastructures to study environmental vibr…
GEMINI: The First Underground Testbed for Seismic Isolation and Interplatform Control in Next-Generation Gravitational-Wave Detectors
Tomislav Andric, Jan Harms, Ilaria Caravella +18
GEMINI is an underground research and development facility dedicated to advancing seismic isolation and control technologies for future gravitational-wave observatories, including…
Reducing suspension control noise with interferometric sensors -- an experimental concept
Nils Leander Weickhardt, Artem Basalaev, Oliver Gerberding
One of the limiting noise sources of ground-based gravitational wave detectors at frequencies below 30 Hz is control-induced displacement noise. Compact laser interferometric senso…
Adjustable picometer-stable interferometers for testing space-based gravitational wave detectors
Marcel Beck, Shreevathsa Chalathadka Subrahmanya, Oliver Gerberding
Space-based gravitational wave detectors, such as the Laser Interferometer Space Antenna (LISA), use picometer-precision laser interferometry to detect gravitational waves at frequ…
Characterizing seismic isolation using convolutional neural networks and Wiener filters
Artem Basalaev, Jan-Niklas Feldhusen, Oliver Gerberding
We investigate seismic motion propagation through a passively isolated mechanical system, using Wiener filters and convolutional neural networks with time-dilation layers. The goal…
