Abstract

This paper describes the optomechanical systems incorporated into the optical module of the breadboard closed loop fiber optic gyroscope. The performance achieved was a rotation rate noise of 5°/hr for 1 second in-tegration, 0.55°/hr for 100 second integration and extrapolated drift of 0.09Whr. The long term (6 hours) bias stability was 1°/hr. A detailed description is directed towards optomechanical systems and related mechanical problems. The results of the investigation into the fiber sensing coil designs and the response of various coil spool geometry configurations to thermal gradients and transients are reported. Also, a sample gyroscope drift run is presented.
