Title
Phase-stepping algorithms : overview and simulations
Author
Abstract
We present a (non-exhaustive) overview of phase-shifting algorithms often used in interferometry. When performing phase-stepping (or -shifting), phase differences in a periodic intensity profile are changed stepwise (or continuously), and the resulting irradiance distributions are recorded at each step (or bucket). The wanted phase can be obtained from the arctangent of the ratio between two combinations of the observed irradiances, according to the phase-shifting algorithm (PSA) used. There are many such combinations and thus different PSAs, each with specific performance and properties. We briefly discuss some error sources which might influence the performance and quality of interferometry measurements. The robustness against these error sources is strongly dependent on the PSA used.
