FSD-HSO Optimization Algorithm for Closed Fringes Interferogram Demodulation

Figure 5

FSD-HSO algorithm applied to demodulate synthetic and real interferograms: (a) normalized interferograms; (b) direct phases of interferograms; (c-d) calculated frequencies along axis, respectively; (e) demodulated phases with ambiguity errors; and (f) correct demodulated phases without ambiguity error.
