ABSTRACT:
A method is described for positioning an optical fiber. The method takes two general forms: (1) The optical fiber is positioned carefully with respect to some predetermined external surface on a stationary holder such that the optical fiber may be later precisely located through use of that surface; and (2) Precisely orienting one or more optical fibers which have been prepositioned with respect to an article such that that article may be similarly precisely oriented. Generally, the methods involve the passing of light through the optical fiber, detecting the output therefrom through the use of a position-sensitive photodetector, and moving the optical fiber so as to achieve a desired relationship to the position-sensitive photodetector.
