Paper Abstract

In classical interference the examined wave front interferes with the plane (model) wave front; whereas in shearing interference two wave fronts interfere with each other - one of them is, in some definite way, transformed in relation to the other. In radial shearing interference two collinear fronts with propagation direction interfere with each other - one of them is transversely magnified in relation to the other. Radial shearing interference can be realized in different systems by various optical elements. Two interferometers measuring the distribution of a refractive index of waveguide preforms are presented below.
