Mitigating effects of nonlinearities in homodyne quadrature interferometers
Johannes Lehmann, Artem Basalaev, Jonathan J. Carter +12
Homodyne Quadrature interferometers (HoQI) are an interferometric displacement sensing scheme proven to have excellent noise performance, making them a strong candidate for sensing…
Testing Compact, Fused Silica Resonator Based Inertial Sensors in a Gravitational Wave Detector Prototype Facility
J J Carter, P Birckigt, J Lehmann +15
Future gravitational wave observatories require significant advances in all aspects of their seismic isolation; inertial sensors being a pressing example. Inertial sensors using gr…
Thermal Correction of Astigmatism in the Gravitational Wave Observatory GEO 600
Holger Wittel, Harald Lück, Christoph Affeldt +10
The output port of GEO 600 is dominated by unwanted high order modes (HOMs). The current thermal actuation system, a ring heater behind one of the folding mirrors, causes a signifi…
