Geophysical Observatory Fürstenfeldbruck
Ludwigshöhe 8, D-82256 Fürstenfeldbruck
FOSREM team is doing a part of the active seismic experiment. All groups installed above 40 sensors and sensors matrix. FOSREM installed four fibre optics sensors ? two FOS3 and two FOS5.

Fibre-Optic System for Rotational Events&Phenomena Monitoring, it is mobile (max. 55x40x20 cm size, 10 kg weight), based on Sagnac interferometer, fiberoptic system for monitoring (via internet or GSM) rotational events and phenomena (in detection bandpass 0.01 -100 Hz). The device will be optimized for measurement of the rotational rate with resolution in range of 1 mrad/s for 1Hz detection bandpass. The above mentioned sensitivity as well as bandpass fulfil expected rotational events and phenomena connected with irregular object movements existing during strong winds, tectonic moves and earthquakes. In this way, the development system is dedicated to monitoring the rotational vibration exiting in such objects as wind power plants, high irregular buildings, bridges, and troubled grounds.
