PARTIALLY COHERENT DIFFRACTION BY A CIRCULAR APERTURE

Abstract

Diffraction patterns of a circular aperture illuminated by partially coherent light can be calculated for a variety of correlation functions and radially varying intensities. The calculation is facilitated by using a theorem, based on the Wolf formulation of coherent theory, that relates the Fraunhofer intensity of a quasimonochromatic spatially stationary source to the Fourier transform of the product of the source autocorrelation function and the normalized source mutual intensity. Curves are presented for the case of a circular aperture with uniform intensity and exponential correlation.
