Abstract

Many practical approaches have been developed for computing the point spread function (PSF) of imaging systems and the subject has been extensively studied for many years, since this has been a classical topic in optics. In recent times, the exact numerical calculation of the diffraction integrals and, hence, of the PSF of image forming systems has been successfully addressed. These methods are based on the determination of the critical points and the semi-periodic zones of the integrand on the plane of the aperture, followed by the summation for each of the zones. In the present work we address a comparison between an approximate calculation method based on the classical approach and the cited exact numerical procedures, mainly regarding the required computational effort involved.
