Paper Abstract

The power spectrum of a diffracted optical field is expanded as the superposition of Young interference patterns produced by all source pairs in the diffracting aperture. It shows clearly that the power spectrum can take negative values for some types of spatially partially coherent optical fields. A renormalization of the definition of the power spectrum based on the etendue is introduced to properly overcome this fact.
