This work applies a holographic setup that uses the photorefractive Bi/sub 12/SiO/sub 20/ and Bi/sub 12/TiO/sub 20/ crystals for real-time holography (RTH). This device is connected with an interferogram-analysis method that uses the phase-stepping technique for quantitative measurement of changes on object and topograph. So we captured holographic interferograms from analyzed surface, and calculated the phase and removed the wrapping of tangent function (unwrapping), using the cellular-automata technique, where obtained good results.
