摘要
太空中γ射线的强度非常高,光纤陀螺中的光纤在如此强的辐照条件下损耗急剧增加,将造成其停止工作。设计了纯石英纤芯的熊猫型偏振保持光纤,采用MCVD工艺制备具有掺F包层的单模棒和应力棒,用打孔镶嵌技术研制出可以应用于航天光纤陀螺系统的保偏光纤。
In the space 7 rays is very intense, the optical fibers using in gyroscope when putting in radiation conditions that the loss of the optical fiber increase fast, and will stop the gyroscope working. So we have designed that the pure silicon core for the PM fiber,used MCVD system to manufacture single mode and boron performs which have fluorin claddings,the new drilling and insetting techinics has been used in fabricating PM fibers that used in spaceflight optical fiber gyroscope.
