| description | The paper deals with the dependence in radial dimensions changes of the workpieces on the angular coordinate based on
experimental data about the geometry of the cross-sections of force rods batch for the production of anisotropic Panda-type
optical fibers. An algorithm of geometrical parameters statistical processing is described, which gives the possibility to find
the similarity in the geometry of the cross-sections of different force rods, and reveal the characteristic shape of the crosssection for all the samples. The algorithm contains the shift of points for dependence changes in radial dimensions of the
workpieces on the angular coordinate in order to find curves with maximum correlation coefficient. Afterwards, the distribution
of the radius values for each angular coordinate is found basing on the obtained curves. It is demonstrated that in case of
the force rods production with variable amount of alloying dopes on the radius via the MCVD method, it is impossible to get |
