构成光纤陀螺敏感器件的保偏光纤环在辐射环境中损耗会增加,陀螺的精度随之降低,从而限制了光纤陀螺在空间中的应用。采用60Co作为辐射源模拟空间辐射环境,对光纤陀螺及其光电器件进行了大量的试验,并对光纤陀螺及其光电器件受空间辐射影响的机理进行了研究,得出光纤陀螺光电器件中保偏光纤环受辐射影响最严重,从而重点分析了光纤陀螺敏感器件保偏光纤环的辐射影响机理,从原理上探讨了保偏光纤环在辐射条件下损耗的增加对光纤陀螺的影响,为光纤陀螺抗辐射加固技术提供了理论基础。
The polarization-maintaining optical fiber loop that constitutes the sensitive device of the optical fiber gyroscope will increase the loss in the radiation environment, and the accuracy of the gyroscope will decrease accordingly, thus limiting the application of the optical fiber gyroscope in the space. 60Co as a radiation source to simulate the space radiation environment, a large number of experiments on the fiber optic gyro and its optoelectronic devices, and fiber optic gyro and its optoelectronic devices under the influence of space radiation was studied, the polarization of the fiber optic gyroscope optoelectronic devices The influence of radiation on fiber ring is the most serious. Therefore, the mechanism of polarization of polarization maintaining fiber ring of FOG sensitive device is analyzed emphatically. The influence of the loss of polarization maintaining fiber ring on the condition of radiation is discussed theoretically. Radiation reinforcement technology provides a theoretical basis.
