THE FIRST 3-DIMENSIONAL RECONSTRUCTION OF A CELESTIAL OBJECT AT RADIOWAVELENGTHS - JUPITERS RADIATION BELTS

For an object where the emission is optically thin, it is shown that t he visibility measured by an interferometer is a sample of the three-d imensional Fourier transform of the object. If the object rotates, the n it is possible to sample this three-dimensional Fourier space adequa tely, and so reconstruct the object in three dimensions. Using this pr inciple, reconstructions of Jupiter's synchrotron radiation belts can be formed. This paper considers the principle and practice of this rec onstruction process.
