  rotary joint
A novel two-way rotary joint (S and P band) is described.
      
For S band rotary joint, VSWR is less than 1.2 over the frequency range from 1.2GHz to 4.4GHz.
      
For P band rotary joint, the structure of the reentrant resonator is used to reduce the length of the rotary joint to about λ/4, and the special and small size requirement is satisfied.
      
Each path includes a rotary joint required for gimbaling the antenna into position at the start of the mission.
      
Field Change Two was the insertion of a rotary joint within the antenna, providing a constant 360 degree rotation capability.

Fiber optic rotary joint(FORJ)is one of passive components,which is used to transmit optical sig- pals from a stationary platform to a rotating platform through a relatively rotating interface.A multi-channel FORJ,by incorporating spatial interconnection and wavelength division multiplexing(WDM)technologies,is proposed and fabricated.It provides high data rate(over GBPS)and hi-directional signals transmission and in- cludes an optical coupling system,isolators and relative WDM components.The insertion loss of...

Fiber optic rotary joint(FORJ)is one of passive components,which is used to transmit optical sig- pals from a stationary platform to a rotating platform through a relatively rotating interface.A multi-channel FORJ,by incorporating spatial interconnection and wavelength division multiplexing(WDM)technologies,is proposed and fabricated.It provides high data rate(over GBPS)and hi-directional signals transmission and in- cludes an optical coupling system,isolators and relative WDM components.The insertion loss of this multi- channel FORJ is measured through a light wave multi-meter(LM),while the output spectrum is monitored u- sing the optical spectrum analyzer(OSA).The maximum insertion loss at wavelength window 1310 nm is about 1.55 dB and the insertion loss at wavelength window 1550 nm is less than 1.20 dB.The insertion loss variation due to rotation at wavelength window 1310 nm and 1550 nm is less than 0.28 dB and 0.43 dB,respectively. The test isolation between the 1 310 nm and 1 550 nm optical signals of all outputs is more than 31 dB.This multi-pass FORJ meets the requirements in most applications.

光纤旋转连接器是一种无源光纤器件,一般被用来耦合光信号通过一个旋转连接面.目前利用光互连技术设计的多通道光纤旋转结构比较复杂,故设计了一种无源多路空间互连光纤旋转连接器.该连接器利用空间光互连技术和波分复用技术传榆多路光信号.测试了多路旋转连接器在1310nm和1550nm波段下的性能,可以得知:在1310nm波段旋转连接器的插入损耗小于1.55dB,旋转变化量最大为0.28dB,1550nm波段的最大插入损耗为1.20dB,旋转变化量小于0.43dB;旋转连接器2个通道之间的隔离度大于31dB.
