光纤信号旋转传输装置的研究

On the Fiber Optic Signal Rotary Transmission Device

光纤旋转连接器件广泛应用于从一端高速旋转平台到另一端静止平台过渡时的场合,是光纤信号旋转传输的关键器件。设计一种单通道光纤旋转连接器,能够在较高转速的场合中,将环境里的振动和其他干扰因素隔绝于连接器之外,并在旋转传输过程中利用其机械结构自适应修正光纤转子与光纤定子之间的相对位置和相对运动,保证光纤信号的高效稳定传输。通过仿真分析和静态实验研究了连接器插入损耗与各个方向上变化量的关系。

Fiber optic rotary joint device,widely used in this transition occasion which transfers from high-speed rotating platform to the other stationary platform,is the key to the fiber optic signal transmission with rotating parts.In the paper,a single channel fiber optic rotary connector was designed to be used in high speed situations and insulate vibration environment and other interference factors outside of the con-nector.During the operation,mechanism was used to adjust the relative position and motion between the rotor and the stator,ensuring the high efficiency and stable transmission of the optical signal.It also inves-tigated the relationship between the connector insertion loss and the variation in all directions through the simulation analysis and static experiments.The device has already applied for the Chinese utility model patent.
