Paper Abstract

The measurement of refractive index profile of the preform or waveguide core can be mad, in a radial interferometer. Two types of radial shearing interferometers have been chosen, designed, and constructed, i.e., double-beam interferometer with prisms and multiple-beam interferometer with etalons.
