Abstract
An angular spectrum of plane waves is used to represent a partially coherent field in a diffracting aperture. The concepts of a characteristic coherence angle and of a characteristic diffraction angle are then used to investigate the behaviour of the diffracted radiation. A simple formalism allows the diffraction pattern to be accurately determined.Keywords
