Method for preparing optical fibres with lateral light emission and installation for implementing same

Abstract

The object of the invention relates to a method for preparing optical fibers (1) each composed of a core (2) surrounded by a sheath (3), in order to create optical fibers with lateral light emission, the method being such that: the translational travel of optical fibers (1) is ensured in front of a station for emitting a laser beam (F), the laser beam (F) directed towards the optical fibers in order to create point-like alterations (4) in the sheath of the optical fibers is moved along a direction (T) transverse to the direction of translation (A) of the optical fibers and along a second way of the transverse direction (T), opposite to the first way.
