Speckled Diffraction Pattern and Source Effect on Resolution Limit in Holography

Abstract

The Speckled Pattern in the Fourier-transform hologram with diffused illumination is described. The distortion term in the reconstructed image is shown to be proportional to the convolution of the intensity distribution of the object against itself, and the point spread function in the image is shown to be proportional to the convolution of the intensity distributions of the sources of the reference and of the reconstruction. The anisotropy in resolution by the source effect is shown with an experimental illustration.
