gyroscope

The agency is now invoking a contingency plan: a “one-gyro” mode that keeps the other functioning gyroscope in reserve.

Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy.

In Optica Publishing Group journal Applied Optics, the researchers report preliminary observational data from the rotational sensor, which is based on a 2-km long fiber-optic gyroscope.

To measure rotation in seismic waves from an earthquake or volcanic activity, the researchers developed a more complex gyroscope based on the Sagnac effect.

Once the researchers have improved the resolution and stability of the single-axis system, they plan to set up a three-axis gyroscope.
