Diffraction at a circular aperture |
 |
| |
Many optical systems use circular apertures rather than slits. The diffraction pattern of a circular aperture, shown in following figure, consists of a central circular bright disk surrounded by progressively fainter bright and dark rings. Analysis shows that the limiting angle of resolution of the circular aperture is
where D is the diameter of the circular aperture.
