Abstract
A new contactless method is presented to measure the variations in the outer diameter of an optical fiber. The fiber is illuminated by a cw He-Ne laser beam that is perpendicular to its axis. The technique is based on an analysis of the light scattered by the fiber in a direction nearly perpendicular to the incident beam. This part of the pattern is very sensitive to a variation in the fiber outer diameter. A method to monitor the outer diameter during the drawing of the fiber has been deduced from the computation of the scattering pattern.
