Relief-phase diffractive optical elements on formed revolution surfaces having the high diffraction efficiency

The equations of microstructure reliefs of the single-layer diffractive optical elements disposed on curvilinear interfaces of two mediums are given. These reliefs provide the demanded form of a wave front and 100 p.c. the diffraction efficiency on one wave length irrespective of number of Fresnel zones. Recommendations about use of the given equations for manufacturing of the double-layer two-relief structures providing high diffraction efficiency within the given spectral range are given.
