Active platform stabilization with a 6D seismometer [PDF]
Applied Physics Letters, 2022 We demonstrate the control scheme of an active platform with a six degree of freedom (6D) seismometer. The inertial sensor simultaneously measures translational and tilt degrees of freedom of the platform and does not require any additional sensors for the stabilization.

A six degree-of-freedom fused silica seismometer: design and tests of a metal prototype [PDF]
Classical and quantum gravity, 2021 Ground vibrations couple to the longitudinal and angular motion of the aLIGO test masses and limit the observatory sensitivity below 30 Hz. Novel inertial sensors have the potential to improve the aLIGO sensitivity in this band and simplify the lock ...

The Development of a New IFOG-Based 3C Rotational Seismometer
Italian National Conference on Sensors, 2021 For many years, seismological research mainly focuses on translational ground motions due to the lack of appropriate sensors. However, because of the development of devices based on Sagnac effect, measuring rotational waves directly comes available.
