光纤陀螺仪及其应用

Fiber optic gyroscope and its application

光纤陀螺是近几十年快速发展起来的用于测量惯性空间角速度的光纤传感器件,由于其自身的优越性,光纤陀螺在许多领域都有较高的应用价值。文章主要阐述了光纤陀螺仪的工作原理、开环光纤陀螺仪和闭环光纤陀螺仪的结构、总结了光纤陀螺的主要性能参数,介绍了光纤陀螺在航海、航天的空间技术、军事、民用领域应用。

Fiber optic gyroscope is an optical fiber sensor of measuring space angular speed in inertial space which has devel- oped rapidly in recent decades, it has high application value as a result of its advantage. In this paper, we mainly illustrate the work principle of fiber optic gyroscope and the construct of open-loop fiber optic gyroscope and closed-loop fiber optic gyroscope and, summarize the main performance parameters of fiber optic gyroscope and introduce the application of fiber optic gyroscope in the ar- eas of navigation, aerospace and space technology, military and civilian.
