    • An optical rotary joint communication apparatus for communicating between a rotor and a stator. Optical sources and detectors are arranged on both the rotor and the stator to provide bi-directional communication. As the rotor rotates, downlink detectors on the rotor sequentially communicate via line-of-sight optical channels with corresponding downlink receivers on the stator. Each downlink receiver is provided a curved mirror reflecting the downlink beam onto the downlink receiver when the rotation angle of the rotor is within a corresponding angle interval. When the rotation angle moves past the angle interval, the downlink beams transition to another mirror and another downlink receiver. The downlink beams are directed predominantly tangential to the rotor circumference. Adjacent downlink transmitters transmit redundant data, and transitions between downlink receivers are staggered for adjacent downlink transmitters to occur at non-overlapping rotation angles in order to prevent loss of data during transitions.
    • 一种用于在转子和定子之间连通的光学旋转接头通信装置。 光源和检测器布置在转子和定子上以提供双向通信。 当转子旋转时,转子上的下行链路检测器通过视线光信道与定子上的相应下行链路接收器顺序通信。 当转子的旋转角度在相应的角度间隔内时,每个下行链路接收机被提供一个将下行链路波束反射到下行链路接收机上的曲面镜。 当旋转角度超过角度间隔时,下行链路波束转变到另一个镜像和另一个下行链路接收器。 下行链路波束主要指向转子圆周。 相邻的下行链路发射机发送冗余数据,并且下行链路接收机之间的转换交错,使相邻的下行链路发射机以非重叠的旋转角度发生,以防止在转换期间丢失数据。
