| 摘 要： | 光纤陀螺仪是惯性系统中目前发展较快的全固态惯性敏感器.在光纤陀螺仪的发展过程中,先有开环式光纤陀螺仪用于战术级和大量民用,而后又发展成为全数字闭环干涉式光纤陀螺仪,逐渐用于导航级惯性系统.到20世纪90年代中期,人们看到了干涉型光纤陀螺仪的高精度发展潜力,开始了精密级光纤陀螺仪及其系统技术的研究工作.从发展角度看,高精度光纤陀螺仪将成为21世纪前期的发展重点.

| Abstract: | Fiber optic gyroscope(FOG) is being fast developed as all-solid inertial sensor in inertial system at present.In the course of FOG development,firstly open-loop fiber optic gyroscope was used in tactical and commercial application,and later it was developed into all-digital closed loop interferential fiber optic gyroscope(IFOG),and gradually applied in navigation-grade inertial system.Until 90s of 20 century,people found the high precision potentials of IFOG and started the research and development of precision-grade FOG and its system technology.From the development view,high precision FOG will become the development focus in the early part of 21 century. |
