摘要
本文阐述了一种新的两芯多模光纤旋转接头的设计原理及实验结果。这种旋转接头采用一同轴光纤 ,一偏轴光纤的结构 ,同轴光纤的信号通过一反射镜 (成 90°)反射入侧面的固定光纤中 ;偏轴光纤的光信号通过一透射镜耦合到另一同步转动的光纤上 ,再将此光纤的另一端置于同轴位置 ,再与另一同轴固定光纤耦合。试验结果表明这种器件已达到实用化的程度。
This paper describes the structure designing and the experiment result of a new duplex multi mode fiber rotary joint. The rotary joint consists of an on axis path and an off axis path. The optical signal of on axis path is reflected to the side and fixed fiber through a reflection mirror (with right angle), the optical signal of off axis path is coupled to the another fiber with synchronous rotation. Then put this fiber into on axis direction and is coupled with another on axis fixed fiber. The experiment result shows that this kind of device achieves practical level.
