Noise Suppression in X-Ray Fourier-Transform Holography Based on Two-Block Fresnel Zone Plate Interferometer with Common Optical Axis

Abstract

Strict requirements were imposed on the sizes of testing sample in the previously suggested scheme of hard X-ray Fourier-transform holography based on a two-block Fresnel zone plate interferometer with common optical axis. The failure of these requirements leads to appearance of noise in the reconstructed image. In this work, the mechanism of noise formation, as well as possibility of its suppression are considered.
