The holographic method and experimental results for recording two-dimensional modulation transfer functions (MTF) of lenses are described. The conditions for hologram-filter recording are determined. The existence of optimum ratio between reference and object beam intensities, at which the results of measuring MTF match with those expected, will be demontrated. The cause of formation of parasite intensity modulation in correlation distribution will be revealed and the way to eliminate it will be suggested. The requirements for granularity of the recording medium for hologram-filters are determined. It will be shown that the results of measuring the two-dimensional MTFs of lenses with symmetrical and nonsymmetrical point spread functions by the holographic method are satisfactorily matching with the expected results and the evidence obtained through harmonic analysis.
