Paper Abstract

A novel approach in fiber-optic gyro (FOG) technology was developed and incorporated into a strapdown inertial measurement unit (IMU). In this approach, optical switches are used to multiplex a single light source, detector, and electronics among three FOG axes. The multiplexed operation of the FOG triad extends the inherent advantages of the single-axis FOG to attain small size, light weight, and low power dissipation and provides a high-performance low-cost IMUs with improved reliability and reduced random drift. A scheme of the triad system is presented.
