Abstract
We present a new algorithm that applies the correlation functions to phase shifting interferometry to recover the phase of a test surface. In this work we make numerical simulations to test the algorithm and the results are verified with real interferograms. The correlation algorithm recovers the phase value with 5% accuracy.
