title: Two-dimensional spatial frequency analysis of the fraunhofer hologram of a small opaque sphere.
abstract: The fact that a Fourier transform relationship exists between the front and back focal planes of a thin spherical lens can be used to obtain the power spectral distribution of two-dimensional holographic data. In particular, this form of optical data processing is considered for obtaining the spectral variation as a function of the recording distance of the holographic intensity distribution caused by illuminating an opaque sphere with plane waves. An approximate, closed form solution for the two-dimensional Fourier transform of this problem is derived.
