Abstract

A diffraction interferometer with a Fresnel zone plate (hologram) situated in the center of curvature of a concave mirror was created to test the shape of surface of spherical and parabolic mirrors. Conditions of minimizing the instrumental error of the scheme to < ?/20 are determined. Methods for suppression of noise and destructive interference patterns are found. Metrological tests of the interferometer were carried out; they substantiated its suitability for tests under service conditions.
