Abstract
Fiber optic alignment methods and apparatus in accordance with the present invention first identify a target beam width incidence on an end of an optical element. The end of the optical element is placed into a beam of light at an axial location relative to the beam of light. The end of the optical element is subsequently moved transversally (perpendicular) to the beam of light until a position of maximum optical power, as measured through the optical element, is identified. A beam width of the beam of light is measured at that axial location. The movement and measurement sequence is repeated at multiple axial locations relative to the beam of light. Linear regression, or an equivalent approach is used, to predict an axial location relative to the beam of light with the target beam width. The end of the optical element is then moved to the axial location with the target beam width.
