Abstract

To deal with both of the fluctuation of background intensity and the random phase shift error, this paper present an efficient and rapid phase extraction algorithm. The parametric equations of Lissajous ellipse are derived by subtraction operations on three random interferograms. Then the elliptic parameters are calculated by ellipse fitting, which is used for phase extraction. It is unnecessary for the algorithm to calculate the random phase shift value and remove the background term, which reduces the algorithm's complexity and shortens the processing time. The effectiveness and reliability of the algorithm are verified by both the numerical simulations and the experiment. The results shows that the algorithm is robust to the fluctuation of background intensity and modulation amplitude.
