Paper Abstract

The measurement method presented in this paper is a destructive method. The refractive index distribution n(x) is calculated on the basis of the reconstructed wave front g (Figure 1.) which is created as a result of plane wave g' going through the examined preform perpendicularly to its axis. When reconstructing wave front g and calculating n(x) it is assumed that the preform and its refractive index distribution have cylindrical symmetry.
