多信道的空间光互联部件,纤维眼的旋转关节,用鸽子棱柱被设计。当鸽子棱柱被旋转时在纵的轴附近的 α 的一个角度,图象旋转 2 α 的一个角度。光互联部件由信号传播系统,整洁的鸽子和开车机制组成。行星的齿轮被用来完成在全部的光互联部件和鸽子棱柱之间的 2:1 的速度比率。C 透镜被采用在信号传播系统联合不同光信号。在静止部分的收到的纤维和旋转部分的播送纤维之间的联合损失被测量。
A multi-channel free space optical interconnection component, fiber optic rotary joint, was designed using a Dove prism. When the Dove prism is rotated an angle of at around the longitudinal axis, the image rotates an angle of 2 at. The optical interconnection component consists of the signal transmission system, Dove prim and driving mechanism. The planetary gears are used to achieve the speed ratio of 2:l between the total optical interconnection component and the Dove prism. The Clenses are employed to couple different optical signals in the signal transmission system. The coupling loss between the receiving fiber of stationary part and the transmitting fiber of rotary part is measured.
