Abstract
The results of scanning method research for testing of diffraction optical elements are shown in this paper. The diffraction efficiency of a specimen of diffraction optical element (Fresnel lens) was measured by the proposed scanning method and by direct (integral) method. Measured data are compared and analyzed. Results of efficiency measurement of diffraction optical element, that produces non-spherical wavefront transformation, are presented and discussed. The parameters of the fulfilled phase profile for these diffractive optical elements are evaluated.
