RT Journal Article T1 Analysis of the principal component algorithm in phase-shifting interferometry A1 Quiroga Mellado, Juan Antonio A1 Vargas Balbuena, Javier A1 Belenguer Dávila, Tomás AB We recently presented a new asynchronous demodulation method for phase-sampling interferometry. 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.
