Paper Abstract

A radial displacement cyclic interferometer parallel beams is used to generate phase shifts. Simultaneously engages an architecture that generates the same moment two interferograms with a phase shift of pi / 2 between them. This phase shift is obtained using optical components. Unlike the arrangements that use a grid in the Fourier plane, where the distance between interference patterns obtained are not adjustable, but is determined by the length of the grid, in the configuration presented, is sufficient to shift one of the reflecting mirrors in order to control the separation between interferograms.. A phase object is used. Interferometric arrangement is presented, and the results obtained experimentally.
