Abstract
In a method for converging the ends of two light waveguides, light energy is coupled into one light wave guide and a portion thereof is coupled out of the other light waveguide. This in and out coupling of the light is undertaken during the axial displacement of one of the light waveguides, whereby the light energy coupled out is continuously measured during the axial displacement. A control signal which is employed for terminating the longitudinal displacement is derived from the discontinuous change in the wave form of the measured light energy coupled out, which discontinuous change occurs at the time of contact between the end faces of the two light waveguides.
