【摘要】 为实现光电跟踪设备中随旋转跟踪架转动的信息传输光纤与固定于设备非转动垂直轴内的信息传输光纤之间的对接,引入光纤旋转连接技术,实现了对接光纤在相互旋转状态下光信息的连续无误传输。为实现信息的双向传输,介绍了采用双通道光纤旋转连接器的常规方法,在此基础上提出单通道光纤旋转连接器与双向光纤模块组合的方法,将波分复用技术与光旋转连接技术组合应用,以提高信息传输性能,简化系统设计结构。所应用的光纤旋转连接器插入损耗﹤2dB,最大转速可达1000rpm,同时光通道的设计实现了带有旋转环节的单纤双向光信号传输。工程实践证明,将单通道光纤旋转连接器与单纤双向光模块组合应用的光通道设计方法可以正确的传输设备信息。更多还原

【Abstract】 To realize the connection between the fiber that rotates with the tracker of the optic-electronic tracking equipment and the fiber that fixed in the non-rotating vertical axis of the optic-electronic tracking equipment,The fiber optic rotary joint(FORJ) technology has been applied,which makes the optical signal be transmitted correctly under the fiber rotating status.The normal method that applying the double-channel FORJ has been introduced,based on which,a method applying single-channel FORJ and double-direction optical module has been carried out to improve the transmission quality and simplify the design structure.The insertion loss of the applied FORJ is less than 2dB and the maximum rotary speed can be up to 1000rpm.Meanwhile the design of the optic channel realizes the double direction signal transmission with rotating movement in single route fiber.The real work shows that the signal of the equipment can be transmitted correctly in the way.更多还原
