摘要

The diffraction theory of aberrations involves the calculation of the Rayleigh-Sommerfeld (RS) integral taking into account that the wave arriving to the diffracting aperture is affected by the aberrations of the optical system and assuming the exit pupil (EP)as the diffracting aperture. This last assumption is just an approximation, since the actual diffracting aperture is the aperture stop (AS) of the system. In this work we show that using the geometrical-numerical approach for the calculation of the RS integral developed at the Optics Laboratory of the Universitat de Barcelona, it is possible to perform the calculation of the point spread function (PSF) of an optical system using as diffracting aperture the AS or the EP. We will prove that the results may indeed be different in some cases and we will present experimetal evidences.
