Abstract

Within the framework of the uniform approach to the interpretation of such coherent-optical methods as holographiy and speckle-interferometry, the method of reflecting diffraction coatings is presented as a variant of speckle-interferometry of a defocused image with filtration of radiation at the recording stage. The mechanism of the phenomenon of wavefront inversion is shown as used for elimination of aberrations in the initial interference pattern and for widening of measurement range in the multistage process of loading of the exami ned object.
