Abstract
We present a simple and effective method for estimating arbitrary phase steps in the presence of noise in phase-shifting interferometry. The method is based on the linear prediction property of the sinusoids. Simulation and experimental results obtained from a holographic interferometry prove the efficiency and feasibility of the proposed method.
