摘要 | This invention provides an apparatus for transferring light between a source (30) of light and a receiver (60) of light potentially having relative motion therebetween precluding physical contact. In its simplest form, the present invention uses one or more looped optical waveguides (40) clad or coated to guide light along the waveguide (40). The waveguide (40) is uncoated or unclad along a window or a portion (44) of the periphery of the waveguide (40). Once the light source (30) is coupled into the end of the waveguide (40), light may be emitted from the window (44) and transferred to the receiver (60). An optical slip ring 80 of the present invention comprises one or more optical fiber waveguides (40) attachable by means of an index matching medium (130) to an optically transparent ring (50). The ring (40) is illuminated by light that is emitted through a window or a portion 44 of the periphery of each waveguide (40). A reflective coating or a shield (140 ) aids in directing light emitted from the waveguide (40) towards the ring (50) and prevents cross-talk in the event that more than one looped waveguide (40) or optical slip ring (80) is used. The ring (50) guides light emitted from the waveguides (40) toward an area, where the receiver (60) is positioned, in an uniform manner ensuring that the receiver (60) is illuminated. |
其他摘要 | 本发明提供了一种用于在光源(30)和光接收器(60)之间传输光的装置,其可能具有相对运动,从而阻止物理接触。在其最简单的形式中,本发明使用包覆或涂覆的一个或多个环形光波导(40)来沿波导(40)引导光。波导(40)沿着窗口或波导(40)周边的一部分(44)未涂覆或未涂覆。一旦光源(30)耦合到波导(40)的末端,光可以从窗口(44)发射并传输到接收器(60)。本发明的光学滑环80包括一个或多个光纤波导(40),其可通过折射率匹配介质(130)连接到光学透明环(50)。环(40)被通过窗口或每个波导(40)的周边的一部分44发射的光照射。反射涂层或屏蔽(140)有助于将从波导(40)发射的光导向环(50)并且在多于一个环形波导(40)或光学滑环(80)的情况下防止串扰用来。环(50)以均匀的方式将从波导(40)发射的光引导到接收器(60)所在的区域,确保接收器(60)被照亮。 |
