Abstract
This work applies a holographic setup that it uses the photorefractive Bi12SiO20 and Bi12TiO20 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.
