Magnification sensitivity of procedure phase contrast, moire contrast and polarization contrast

The algorithm of nonlinear processing of interferogram offered earlier is briefly stated, allowing to increase their sensitivity down to limiting. The opportunity of adaptation of this algorithm for magnification sensitivity of procedure phase contrast, moire contrast are shown. Procedure prototype of this method is the analog nonlinear signal processing of holographic interferometry of phase patterns.
