摘要：

A new area of fiber-optic Sagnac interferometer application is presented and discussed. The fiber-optic sensor described in the paper, in well-known classic fiber-optic gyro configuration, has been designed for a detection of the rotational seismic events. The basic system optimisation for a detection rotation only without conversion for angular changes distinguishes this system from the gyro application. On the other side, the detection of absolute rotation can give an advantage for this system in compare to other rotational seismometers, which calculate rotational events in indirect ways. The comparison of data from the described fiber-optic rotation seismometer and two antiparallel pendulum seismometers are also presented.
