The method is based in the principal component analysis (PCA) technique. In the former work, the PCA method was derived heuristically. In this work, we present an in-depth analysis of the PCA demodulation method.engAnalysis of the principal component algorithm in phase-shifting interferometryjournal articlehttp://dx.doi.org/10.1364/OL.36.002215http://www.opticsinfobase.org/open access535OpticsÓptica (Física)2209.19 Óptica Física
