Abstract

Phase-shifting (PS) is a well-established technique for phase retrieval in interferometry that requires a series of intensity measurements with known or unknown phase-steps. The objective of this work is determinate a tunable PS algorithm that minimize the error in the reconstructed phase when the images have additive random noise and the phase-step was determined with certain error. Simulations to show the performance of the algorithm will be presented.
