Short abstract: Lenses and mirrors that are customary in classical optical systems have smooth gradually variable surfaces preserving geometrical wavefronts structure. In contrary, photonics crystals, metamaterials, plasmonic and diffractive structures feature discontinuous fine structured surfaces. Digital holography also considers a discrete set of points for modeling of 2-D and 3-D holograms. The lecture addresses a basic problem of merging the classical optical design with diffractive and subwavelength structures. It is shown that an enabling issue is in understanding of local beam transformation equations occurring in ray-tracing design. Another issue is to implement local transformation by a relevant physical mechanism of light diffraction or interaction with photonics structures. Relation between paraxial Fourier optics and generalized optical design is discussed.
