    摘要: A method and apparatus are disclosed for aligning and maintaining the alignment of the transmitting unit and the receiving unit in an optical wireless communication system. The receiving unit includes an optical bundle positioned at the focal point of an objective optic element. The optical bundle is comprised of an array of optical fibers, arranged surrounding the receiving fiber. The receiving unit also includes a number of detectors that measure the optical signal strength on a corresponding fiber in the optical bundle. The array of fibers is used to detect the location of the received signal relative to the receiving optical fiber and to provide feedback to adjust the orientation of the optical bundle to optimize the received signal strength. When misalignment occurs between the received signal and the receiving fiber, some of the incident received signal will be captured by one or more of the outer optical fibers. The amplitude of each of the generated signals are then compared to each other, thereby giving a direction in which to drive the optical bundle back into alignment with the received signal. The present invention provides automatic tracking using the information-carrying optical signal, without the need for a separate laser.

    摘要: A method for controlling a bore diameter of an optical fiber ferrule is disclosed. The diameter of the bore is controlled by collapsing the ferrule around a rod inserted in an over-sized bore formed therein. The diameter of the rod is selected to match the diameter of the optical fiber to be supported by the ferrule. Thus, after the rod is subsequently immersed in liquid nitrogen removed from the ferrule, the ferrule has a bore diameter which is defined by the diameter of the rod. Suitable materials for the ferrule and the rod include glass and metal, respectively.

    摘要: An apparatus for aligning the cores of the two optical waveguides. The apparatus includes a control loop for receiving an aligning signal launched through the core of one of the optical waveguides. The control loop may effectuate the aligning signal to propagate through the cores of the optical waveguides. The control loop may include a detector for generating a detecting signal in response to detecting the aligning signal. Moreover, the control loop may include a machine-vision system for generating a manipulation signal in response to the detecting signal. The control loops may also include a controller for physically aligning one of the optical waveguides with respect to the other optical waveguide in response to the manipulation signal. The controller may perform the physically alignment by means of a robotic tool. The apparatus may also include a means for splicing the optical waveguides.
