Abstract
For identifying the local distribution of light waveguides in two groups to be aligned to one another, the groups are displaced at least once relative to one another transversely relative to the longitudinal axes of the light waveguides to be investigated in at least one plane. The chronological curve of the intensity distribution of the light coupled from the one group into the other group during the displacement is identified and evaluated. For optimally aligning the waveguides with two groups, an intensity distribution for each group is obtained and the distributions are compared to find an alignment which produces a maximum overlap. A splicing operation may be then conducted with the groups thus aligned, and the same technique can then be used to control the splicing as well as to check the quality of the splice.
