Diffraction: Fresnel and Fraunhofer regimes, minimum distances, linearity, relation input/output.
Examples: rectangular and circular apertures, amplitude and phase diffraction gratings.
Focusing system amplitude transmission function: quadratic phase and pupil function.
Abbe theory. Rayleigh criterium.
Relation between fields at infinity (Fraunhofer) and the focal plane of lenses / antennas.
Imaging a point source: impulse function and Point Spread Function, analysis of the required approximations.
Concept of generalized Pupil function for systems with aberrations
