The van cittert-zernike theorem
Aperture synthesis The van Cittert–Zernike theorem is crucial to the measurement of the brightness distribution of a source. With two telescopes, a radio astronomer (or an infrared or submillimeter astronomer) can measure the correlation between the electric field at the two dishes due to some point from the source. … See more The van Cittert–Zernike theorem, named after physicists Pieter Hendrik van Cittert and Frits Zernike, is a formula in coherence theory that states that under certain conditions the Fourier transform of the intensity distribution … See more The mutual coherence function for some electric field $${\displaystyle E(t)}$$ measured at two points in a plane of observation (call them 1 and 2), is defined to be where See more Suppose we have a situation identical to that considered when the van Cittert–Zernike theorem was derived, except that the … See more • Born, M. & Wolf, E.: Principles of optics, Pergamon Press, Oxford, 1987, p. 510 • Klein, Miles V. & Furtak, Thomas E.: Optics, John Wiley & Sons, New York, 1986, 2nd edition, p. 544-545 See more Let $${\displaystyle XY}$$ and $${\displaystyle xy}$$ be respectively the cartesian coordinates of the source plane and the observation … See more The van Cittert–Zernike theorem rests on a number of assumptions, all of which are approximately true for nearly all astronomical sources.
