Control of optical fibers positioning at manufacturing optical connectors and welding splices

The matched filtration as an autoconvolution of an optical field distribution, emitted by core at longitudinal illumination or focused by fiber at transversal illumination is used for fibers core axes offset determination. The autoconvolution maximum coordinates correspond to the core center double displacement concerning base coordinates. The technique mathematical thesis, results of a computer modeling and experimental researches on the acting technological equipment are adduced.
