“…The first work on PCA as nPSA was presented as a linear algorithm which could demodulate any set of phase-shifted fringes, almost error-free [33]. Afterwards this was found not to be exact and several attempts have been made to improve plain PCA [35,[38][39][40]. However, the PCA can be combined with AIA, obtaining a PCA-AIA algorithm which eliminate the phase-errors left by plain PCA [35].…”

“…In addition, PCA is inherently resistant to harmonics or/and other issues such as over or under exposure that might arise from image capture. If necessary, the proposed algorithm can be improved using iterative least squares techniques [11][12].…”

“…In recent years, many achievements related to PSI have been presented, especially phase retrieval and phase shift extraction [3][4][5][6][7][8][9][10]. In standard PSI, to retrieval the measured phase, a sequence of N-step phase-shifting interferograms (N ≥ 3) with the known phase shift are required.…”
