Two-Step Phase-Shifting Algorithm Based on the Quadratic Spatial Filtering of Interferograms
By using the quadratic spatial filtering (QSF) operation of interferograms, we propose a fast and accurate phase retrieval algorithm in 2-step phase-shifting interferometry (PSI), in which both the interference signal separation and blind phase shift estimation can be realized. Compared with the exi...
