摘要：

In the paper a new areas of the fiber-optic-Sagnac interferometer applications are discussed. The presented devices basing on well-known optical gyroscope configuration are optimized for detection of other special physical quantities. Generally it is a rotational seismometer designed for calibration of the other electromechanical types of such devices, as well as a new sensor for detection of rotational seismic events. The detection of absolute rotation by the system is advantageous in comparison to the other rotational seismometers, which calculate rotational events in indirect ways. The paper describes comparison of the data obtained from the fiber-optic rotational seismometer and the electromechanical one. Moreover, on this base the construction of new system with resolution 10 E-8 rad/s is also presented in this paper.
