Integrated Optics : A Practical Solution For The Fiber-Optic Gyroscope

Abstract

Integrated optics is appearing as a practical solution for the fiber gyroscope. We describe quarter of a liter and tenth of a liter brassboards using such a multifunction circuit (in a so-called "Y-tap" configuration). Random walk performance of 2 x 10-°/√h has been demonstrated as long term bias stability of ± 0.3°/h over a 15°C temperature range.
