摘要
光纤旋转连接器是一种广泛应用于军事国防、工业等领域的关键器件。光纤旋转连接器的功能为将光信号从旋转平台传输到静止平台。介绍了光纤旋转连接器的具体用途,描述了单通道光纤旋转连接器和多通道旋转连接器的工作原理和具体制作方法。介绍了国外光纤旋转连接器的发展动态和技术指标。制作了插入损耗小于2 dB的单模单通道光纤旋转连接器。进行了光纤旋转连接器的温度冲击对比实验,测试结果好于国外产品。分析了光纤旋转连接器的特点。重点介绍了光纤旋转连接器在军事国防的各个领域的用途。
The fiber optic rotary joint has been widely used in the field of national denfence and industrial design.The function of fiber optic rotary joint is to communicate crucial data from rotating platform to stationary platform.The specific use,working principle and production methods of single-channel and multi-channel fiber optic rotary joint were described.And foreign fiber optic rotary joint developments and technical specifications were introduced.The insertion loss of a fiber optic rotary joint depended on the mechanical misalignments of the fiber collimator.A single mode single-channel fiber optic rotary joint whose insert loss was below 2 dB was designed.Comparative experiment of temperature impact for fiber optic rotary joint was carried out.Test results were better than that of the foreign products.The characteristics of fiber optic rotary joint were analyzed.Finally,the applications of fiber optic rotary joint in national denfence have been introduced.
