ORIENTATING OPTICAL FIBRES

摘要

A method and apparatus for setting the orientation of an optical fibre having at least one planar section extending along its length comprises a light source for generating a beam of light which impinges on the fibre. Light reflected by the fibre is detected by a light detector and the fibre is rotated by means of a tube into which it is inserted while the intensity of the detected light is monitored. When the intensity becomes a maximum then the planar face is facing in a known direction.
