Abstract

Using phase-shifting interferometry [Malacara, 1992], which basic equation iswhere a (x,y) is the modulation intensity, ϕ(x, y) is the phase, b(x,y) is the background intensity and al is the phase value for the lth measurement. With the equation (1) we generated N numerical interferograms.
