In recent years, optical fibers have found extensive use in special environments, including high-energy radiation scenarios like nuclear explosion diagnostics and reactor monitoring. However, radiation exposure, such as X-rays, gamma rays, and neutrons, can compromise fiber safety and reliability. Consequently, researchers worldwide are focusing on radiation-resistant fiber optic technology. This paper examines optical fiber radiation damage mechanisms, encompassing ionization damage, displacement damage, and defect centers. It also surveys the current research on radiation-resistant fiber optic design, including doping and manufacturing process improvements. Ultimately, it summarizes the effectiveness of various approaches and forecasts the future of radiation-resistant optical fibers.
近年来，光纤在特殊环境中得到了广泛应用，包括核爆炸诊断和反应堆监测等高能量辐射场景。然而，诸如X射线、伽马射线和中子等辐射暴露会损害光纤的安全性和可靠性。因此，全球研究人员都在关注抗辐射光纤技术。本文研究了光纤辐射损伤机制，包括电离损伤、位移损伤和缺陷中心。它还综述了当前抗辐射光纤设计的研究，包括掺杂和制造工艺改进。最终，它总结了各种方法的有效性并预测了抗辐射光纤的未来。
