Abstract
An alignment apparatus for determining angular coordinates for offset and intersecting optical fibers in a mechanical optical switch has an analytical apparatus for imaging the end faces of the ferrules containing the opposing optical fibers of the switch for determining the respective axes of rotation of the mounting members, the locations of the optical fibers in the respective mounting members and coordinates of the optical fibers relative to the axis of rotation of the respective mounting members, the location of at least one reference point within one of the mounting members, and the relative angular coordinates of intersecting points between each of the closed curves of the plurality of optical fibers within the second mounting member and the closed curve of the first optical fiber as a function of the offset of the first and second mounting members and the reference point. The relative angular coordinates are passed to a measurement alignment apparatus for determining the angular coordinates of the intersecting points between each of the plurality of optical fibers and the first optical fiber as a function of optimally aligning the first optical fiber with each of the plurality of optical fibers.
