Considering the characteristics of the FOG, a scheme of controlling the driving current by the feed back light from the coupler and detector of FOG was discussed. 结合光纤陀螺特点，讨论了从光纤陀螺耦合器和探测器提取信号进行光反馈控制的方案。
Optical feedback self-mixing interferometry is an emerging sensing and measurement technique, which is quite different with traditional double-beam interferometry. 光反馈自混合干涉技术是一种新浮现的有别于传统双光束干涉的一类新的测试技术。
