Core position identification at the optical fibers connection by an autoconvolution method

The automated control technique of optical fibers positioning for switching fiber-optical component manufacturing is considered. The agreed 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 fiber 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 simulation modeling and experimental researches on the acting technological equipment are adduced. The offered technique is more effective than traditional methods of a filtration in frequent or space area, as requires a smaller amount of mathematical operations, does not put forward a problem of filter pulse response direct determination and ensures high accuracy parameters.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering.
