wave aberration

wave aberration

The difference between the wavefront W of ideal imaging with no aberrations (Gauss imaging) and the wavefront S in actual imaging with various aberrations is called “wave aberration.” It is defined as the optical path difference between wavefronts W and S measured along an electron trajectory given by geometrical optics. The wave aberrations neccessary for the interpretation of a high-resolution image are axial aberrations (spherical aberration and parasitic aberrations).
