Paper Abstract

The vertical and horizontal seismometers based on fiber-optic Mach-Zehnder interferometer are proposed and tested. The sensing element of seismometers is implemented as a multiturn optical fiber coil which allowed to obtain for vertical seismometer sensitivity to acceleration 10–7 m/s2 and for horizontal seismometer sensitivity to displacement 10-9 m . Stability of the seismometer operation is provided by feed-back control of the interferometer working point. The possibility of registration of weak seismic signals are demonstrated.
