ABSTRACT:
A method for recognizing an angular error between a fiber end, which is aligned with another fiber along a desired axial orientation, by scanning one of the optical fibers along a scanning path, shifting the fiber to a second position in a direction parallel to the desired axial orientation for the fiber and scanning the optical fiber in the second position along the same measuring path, evaluating the intensity of each of the scans to determine the skewed angle for the fiber from the desired axial orientation.
