Abstract
We present a parallel polarizing phase shifting interferometer based in a Double Cyclic Shear Interferometer (DCSI) to analyze transparent samples. The system itself has the advantage of retrieve the derivative phase data map directly and ,due of its configuration itself, it presents betters stability against external configurations than other types of interferometers. The DCSI generates two π-shifted interferograms, which are recorded by the camera in a single-shot. The optical phase is processed by the four-step algorithm. Related simulations and experimental results obtained for transparent samples are also presented.
