Spatial Filtering of Lateral-Shear Interferograms in the Case of Double-Exposure Recording of a Lens Fourier Hologram of a Mat Screen. II

Distortions of lateral-shear interferograms in fringes of infinite width due to hologram aberrations are analyzed in a third approximation for a complex field amplitude. The interferometer sensitivity range in the field is shown to increase in the case where a Fourier hologram of a mat screen is recorded using a negative lens, two identical subjective speckles of two exposures are superimposed in the hologram plane, and errors of control are eliminated.
