High-precision fiber optical gyroscope with linear digital output

The interferometric fiber-optic gyroscope (FOG) has evolved from pioneering physics experiment to a practical device that is now in production. Today, it is now accepted among inertial guidance and navigation specialists that FOG is strong contender for many civilian and military applications. The opportunity of commercial production of precision fiber-optical gyroscope is directly determined by the level of technological base and its main components like polarization maintaining optical fibers and integral optic components.
