Abstract

A new method of holographic interferograms interpretation, based on the scalar diffraction theory is proposed. This method allows to determine the field of displacements only from measurement of fringe visibility in holographic interferograms. It may be also used as a new method of zero-order fringes localization. The general form of the light intensity distribution in interference field, dependent on the intensity-and-phase spatial spectrum of a light source illuminating an object and on the phase modulation function of object is given. Some cases of object illumination and object surface structure are discussed.
