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.
