Merging classical optical systems with diffractive and subwavelength structures

Lenses and mirrors that are customary in classical optical systems have smooth gradually varying surfaces preserving geometrical wavefront structure, but provide limited degree of freedom in optical design. Diffractive optical elements open new opportunities in optical wavefront transformations in such applications as imaging optical communications, ophthalmology, microscopy and multimedia. Important to keep a phase function in diffractive design close to smooth geometrical optics solutions and understand a local wavefront slope and curvature transformation.
