Abstract
If the mutual intensity of partially coherent illumination is periodic in the lateral direction then it is also periodic in the longitudinal direction. This statement is proved for quasi-monochromatic light and for a cosine periodicity. Next an experimental set-up for the production of periodic mutual intensities is proposed. Finally, the theoretical result is generalized to other than cosine-shaped periodicities.Keywords
