"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: " - Optics opd
