Abstract
A visibility-dependent depth of focus is developed for incoherent sinusoidal sources. This analysis is based on a derived relationship between the visibility and the optical transfer function (OTF). The formalism developed is general for any aperture topology and arbitrary orientation of sinusoidal sources. To illustrate the application of the method the cases of an annular aperture and a Gaussian aperture are analyzed. It is found that as the level of defect of defocus increases, the maximum visibility for which a particular spatial frequency can be resolved decreases.
