Paper Abstract

The optimization of fiber-optic Sagnac interferometer as a sensor for the investigation of seismic rotational waves is presented in this paper. The main parameter of this optimization is maximum system sensitivity for absolute rotation in the limited range of expected velocities. The main system construction bases on the FOG minimum configuration, however the detection by system only rotational velocity without covering it on angle changes needs other approach to this system. The presented in paper theoretical and experimental investigation shows that such system can be made on base of a standard single-mode optical fiber, however needs operation on depolarized light.
