The proposed work shows that the application of special focusing reflective diffraction coatings leads to a significant gain both. in aperture ratio of a speckle interferometer and in the quality of the interference pattern produced. Possible circuits have been studied for the obtaining of interference patterns of the derivatives up to the second one inclusive of the deformed object surface points shift function in one and the same exposure. By way of experimental verification interferograms of bendings w, angles of the normal swing in respect to the surface w' and curvatures wt" of a round plate restrained along the edge have been received by means of the suggested devices.
