Precise phase demodulation of single carrier-frequency interferogram by pixel-level Lissajous figure and ellipse fitting
Phase demodulation from a single carrier-frequency fringe pattern is becoming increasingly important particularly in areas of optical metrology such as dynamic interferometry, deflectometry and profilometry. The Fourier transform (FT) method and the spatial-carrier phase-shifting technique (SCPS) ar...
