The OPD is positive if the aberrated wavefront leads the … WebA lens that is focused onto the point source will have optics that change the spherical wave front into a planar wave before it passes through the pupil or aperture stop. Often, additional lens element refocus the light onto a sensor or photographic film, by converting the planar wave front to a spherical wave front, centered onto the image plane. WebWarren Smith provides a method to relate MTF of a given frequency to the wavefront deformation (OPD) (Smith, 1985). This method enables for changes in aberrations to be found as a function of system perturbations. The following are the relations Smith provides between OPD and ray-traced aberrations; the OPD are in units of waves: fk banco
