Even for the simplest nontrivial aberration, defocus, and for a circular pupil, there is no theoretical closed-form expression for the optical transfer function (OTF). By using a simple approximation for the error at the pupil, we provide a simple yet accurate approximation for the OTF of a defocused system. We then generalize this approach to generic quadratic aberrations, including astigmatism.
