Centering and seaming the determination of the angular offset the fiber between the optical fiber having an optical axis asymmetry

摘要

(57) Abstract The occasion where optically optically, angular offset between the heterogeneous field inside the transparent body such as fiber core of the stress centralized zone (7) of the PM optical fiber which is placed, in the angular start position of especially option between axial asymmetry or 2 core optical fibers (3 '') is decided, while turning to the angular position which differs around that length axis it illuminates the end of the fiber. It passes by aforementioned fiber end in the angular position which differs, it decides the difference (h) with the light where that position corresponds to the center section of the fiber and it passes by the end of the fiber and the light which corresponds to the field of the fiber where that position is immediately outside aforementioned middle position. These differences (h) which are thought function in angle of rotation form the curved line of the fiber end. Comparing this curved line, form of curved line moves agrees best parallel to new angular position. As for angle between curved line at this angular position, the plane surface in that start position which for example passes by the stress zone (7) or the fiber core (3 '') (8,8) is given. Making use of this angle, in order these plane surfaces (8,8), therefore for the stress zone with fiber end (7) or the core of the fiber core (3 '') to be agreeable mutually, fiber end it turns.
