摘要
针对光纤旋转连接器(FORJ)普遍存在着结构复杂、损耗过大和转速低等问题,提出了一种高速单通道单模FORJ结构,并对其性能进行了相关的实验测试,对FORJ中光信号传输时的损耗进行了分析研究。实验结果表明:所设计的单通道单模FORJ能够在8000 r/min的高转速下传输光信号,损耗量为19.6 dB,且能承受的最大冲击载荷为20 m/s^(2),旋转输入轴的最大径向振幅为0.63 mm,能够适应较为恶劣的工作环境。
In view of the problems of complex structure,excessive loss and low speed in the fiber optic rotary joint(FORJ),a high-speed single-mode FORJ structure is proposed,and its performance is tested.The loss of optical signal transmission in FORJ is analyzed and studied.The experimental results show that the designed single-channel single-mode FORJ can transmit optical signal at high speed of 8000 r/min,the loss is 19.6 dB,the maximum impact load is 20 m/s^(2),and the maximum radial amplitude of the rotating input shaft is 0.63 mm,which can adapt to the harsh working environment.
