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…
Dual balanced readout for scattered light noise mitigation in Michelson interferometers
André Lohde, Daniel Voigt, Oliver Gerberding
Ground-based gravitational wave detectors use laser interferometry to detect the minuscule distance change between test masses caused by gravitational waves. Stray light that scatt…
Integrating high-precision and fringe-scale displacement sensing using heterodyne cavity-tracking
Shreevathsa Chalathadka Subrahmanya, Christian Darsow-Fromm, Oliver Gerberding
We present a heterodyne stabilized cavity-based interferometer scheme that can serve as a compact and high-sensitivity displacement sensor with a fringe-scale operating range. The…
The Lunar Gravitational-wave Antenna: Mission Studies and Science Case
Parameswaran Ajith, Pau Amaro Seoane, Manuel Arca Sedda +83
The Lunar Gravitational-wave Antenna (LGWA) is a proposed array of next-generation inertial sensors to monitor the response of the Moon to gravitational waves (GWs). Given the size…
High Precision Inertial Sensors on a One Inch Diameter Optic
Jonathan J Carter, Pascal Birckigt, Oliver Gerberding +1
Compact, high-precision inertial sensors are needed to isolate many modern physics experiments from disturbances caused by seismic motion. We present a novel inertial sensor whose…
On the Development of an RFSoC-Based Ultra-Fast Phasemeter With GHz Bandwidth
Shreevathsa Chalathadka Subrahmanya, Christian Darsow-Fromm, Oliver Gerberding
Precise measurements of the frequency and phase of an electrical or optical signal play a key role in various branches of science and engineering. Tracking changing laser frequenci…
