A computer aided local estimation of fusion splice loss for graded-index optical fibers is proposed. Spliced fiber outer diameter deformation is extracted by image processing technique. The relation between deformation at the splice portion and splice loss is obtained experimentally. It is possible to eliminate large loss splices automatically using the splice portion appearance.
