Seidel aberrations in optical processors due to diffraction of a quasi-spherical wavefront

In optical processors the structure (objector filter) can be considered as a superposition of Fourier components, that is of sinusoidal gratings of different spatial frequencies and orientations. If these gratings do not work in parallel light, aberrations will appear. The fourth-order aberration fu...
