Abstract
The angular extent of a hologram’s zero-order light is derived from that of a set of collimating lenses. The effect of a reference source of nonzero area is obtained from the Airy disk of a lens. The finite temporal coherence of the reference source is modeled in terms of the depth of field of a lens. Finally, sampled holograms, such as those usually obtained in microwave or acoustical work, are modeled by a lens with a complicated pupil function. For the first time, these disparate topics in holography are treated in terms of simple lens properties; such a treatment is extremely useful for gaining an increased intuitive understanding of holography.
