| Zusammenfassung |
| In this contribution we present a full characterization of the first three component
interferometric fiber-optic gyroscope (IFOG) especially designed for the needs of seismology.
The sensor is called BlueSeis3A and is manufactured by iXBlue, France. It is developed in
the framework of the European Research Council Project, ROMY (Rotational motions – a
new observable for seismology). To fully explore the benefits of this new seismic observable
especially in the fields of volcanology, ocean bottom seismology and geophysical
exploration, a portable rotational motion sensor has to fulfill certain requirements
regarding dynamic range, portability, power consumption and sensitivity to changes
in ambient temperature and magnetic field. For BlueSeis3A, power consumption
is in an acceptable range for a portable and field deployable instrument. We will
quantify sensor self noise by means of operating range diagrams as well as Allan
variance and show results from tests on thermal and magnetic sensitivity. Tests on
orthogonality and sensitivity to linear motion complete our full characterization. |
