The Fiber-optic GyroscopeThis reference presents a system analysis of the fibre-optic gyro. Drawing on 15 years of research and developments, it describes the concepts that have emerged as the preferred solutions for obtaining a practical device, and provides access to the information needed to know about optics, single-mode fibre optics and integrated optics to understand the fibre gyro. |
