Paper Abstract

An alternative method for phase-shifting interferometry of two steps by using a speckle interferometer is proposed. It is shown that the introduced phase-step could be unknown because the use of an appropriate fringe-pattern processing. The acquired fringe patterns are processed by well established phase-shifting algorithms in order to compare these results with our proposal. Numerical phase difference between two states of phase object is compared with theoretical method using electronic speckle pattern interferometry (ESPI) . Simulated and experimental results are provided.
