Abstract
The spatial techniques providing the robust technique for phase measurement are presented specifically the phase-stepped and Fourier transform methods. The grating phase-shifting approach is implemented into holographic speckle and moire interefrometry arrangements. The three-channel versions of these interferometers enable the measurements of dynamic events and in adverse conditions. For the technique where the fringes with carrier frequency are avaliable the refinements of Fourier transform method to facilitate measurements are presented. The advantages and disadvantages of these two spatial methods in comparison with temporal techniques are given.
