  • Abstract
    In longwave holography, the detection of the incident object wavefronts in the recording plane is accomplished by means of an array of detectors, or by a single scanning detector. It is shown that the retrived image is a function also of the Fourier transform of the spatial location of the detecting elements in the recording plane. Analysis and experiments show that one of the best image performances is predicted with the "Anti Fresnel Zone" geometrical arrangement.
