光纤陀螺小型化技术研究进展

Research progress on miniaturization technology offiber-optic gyroscope

小型无人机(UAV)、小型自主水下机器人(AUV)以及战术导弹等对自身导航定位模块除了精度要求之外,还需要具有小体积、低功耗、高可靠性等特点。目前广泛应用的光纤陀螺仪(FOG)由于体积原因,制约了其在上述领域的应用。随着无人智能技术的进一步发展,小型化、中精度、低成本的战术级光纤陀螺仪必将具有不可估量的应用前景。介绍了光纤陀螺技术基本原理、发展历程、现状以及光纤陀螺小型化关键技术,最后进行了总结展望。

Miniaturization unmanned aerial vehicle(UAV),miniaturization autonomous underwater vehicle(AUV)and tactical missiles require their own navigation and positioning modules to have characteristics of small size,low power consumption and high reliability in addition to precision requirements.At present,widely used fiber-optic gyroscope restricts its application in the above fields due to its volume.With further development of unmanned intelligent technology,miniaturized,medium-precision and low-cost tactical fiber-optic gyroscopes will have immeasurable application prospects.Basic principle,development history,current situation and key technologies for miniaturization of fiber-optic gyroscopes are introduced,and summary and prospect are made.
