全抗輻射光纖光源

Improving Depression, Hope, and Quality of Life in Dialysis Patients Using Health Promotion Education Groups

本發明以獨特的光致退火技術，達到即時修復因輻射照射引起的摻稀土元素光纖退化機制，可將光通訊及光感測系統中使用摻稀土元素光纖的光源功率或光放大器增益的耗損，以幾近即時的方式完全修補回來，不受輻射照射的影響。目前本發明製造的抗輻光纖光源除已獲准使用於福衛七號自主衛星姿軌控制系統的太空級光纖時螺儀上，也可以應用於，如核能發電廠，輻射設施的關鍵參數偵測上。另外在太空雷射光通訊應用上，美國噴射推進實驗室已成功驗證太空與地面的高速雷射光通訊，此一先進雷射光通訊系統，若能配合本發明成為全抗輻設計，將可大幅提升該系統於太空中的可靠度與壽命。本項發明獲得2014年德國紐倫堡國際發明展社會組金牌獎。 This invention is based on a unique photo-annealing technique capable of a total recovery of radiation-induced degradation onto rare-earth doped fibers. Degradations such as radiation-induced power or gain loss of rare-earth doped fiber light source or fiber amplifier modules as part of an optical communication or fiber sensing system were recovered completely in near-real-time. This photo-annealing technique that enables a complete radiation-hardened performance on rare-earth doped fibers is the first of its kind in the world. The current invention has been adopted into the design of a radiation-hardened fiber light source for space-grade fiber-optic gyros residing in the attitude and orbit control system of the FORMOSAT-7 NSPO-built satellite. The technology is also suitable to be deployed to monitor key parameters of nuclear facility and equipment. In addition, for important space optical communication applications, US NASA Jet Propulsion Laboratory(JPL) has demonstrated successfully a high-bandwidth laser communication link between space and ground stations. The current invention can be incorporated to make JPL’s laser communication system totally radiation-hardened to greatly improve its reliability and usage life in space. This technology’s patent received gold medal recognition in the 2014 iENA Nuremberg Inventions.
