Abstract

By analysing the diffraction pattern obtained by side illumination of an optical fiber with a parallel beam we obtain information about the fiber geometry. In this paper we discuss shortly the solution of the boundary value problem and the calculation of the diffraction pattern of graded-index fibers. We describe the optics and the signal processing electronics of a set-up that is used to measure the outer diameter and the core diameter of graded-index fibers during the drawing process.
