摘　　要：本文介绍了干涉式光纤陀螺的基本原理，评述了光纤陀螺的信号检测方法。对开环和闭环检测方案进行了比较分析。分析认为全数字闭环检测方案优于其它方案，更适合于研制高精度的光纤陀螺。最后介绍了信号处理硬件系统的功能和组成。The basic principle of interferential FOG and its signal detecting methods are reviewed in this paper. The advantages and disadvantages of signal detections for the FOG are also analysed in open and closed loops respectively. The results indicate that the signal - processing scheme with full - digital closed loop for FOG is better than others, especially for high grade FOG. Finally the functions and the components of signal processing hardware are presented.
