Abstract
Starting from the Culgoora paradox, the number of degrees of freedom of an image from a pupil of point-like elements has been determined. The influence of the pupil geometry and of the coherence characteristics has been examined. The results show that striking differences can exist between coherent and incoherent illumination.Keywords
