Utilization of Fiber-Optic Gyros in Inertial Measurement Units

A. Matthews

Abstract:	Fiber-optic-gyro technology has been developed to a point where these gyros are now being introduced into advanced engineering models of the next generation of inertial measurement units (IMU). This article covers the operating principles of the interferometric type of fiber-optic gyroscopes together with a brief comparison against ring-laser gyroscopes. Recent flight test data are presented of an IMU employing fiber-optic gyro sensors. Finally the unique characteristics of the fiber-optic gyro are discussed with particular emphasis on the role they will play in future fault-tolerant IMUs.
