ABSTRACT:
A portion of a fiber to be positioned is transversely irradiated by means of an ultraviolet light source. The source emits ultraviolet light of such a wavelength that fluorescence is produced in the core of the fiber. The visible light produced in the core by the fluorescence is used to make observations for visually controlling the position of the fiber. In this manner, cores of light conducting fibers can be positioned very accurately even when they are arranged eccentrically in the cladding.
