Low loss connection of fiberoptic rotary is realized by direct coupling of fiber, which is photon crystal fiber (PCF).
该设计以光子晶体光纤为基础，采用直接耦合的方法实现低损耗的光纤旋转连接。

The part of optic paths includes optical fiber strain sensor, lamp-house, optical fiber coupling instrument and light dispersion equipment.
光路部分包括光纤传感器、光纤、光源、光纤耦合器以及设计的解调光路部分。

But spurious polarization coupling caused by many factors will affect the performance of PMF, and therefore reduce fiber-optic gyro's quality and measuring precision.
