Abstract :
The "Abbe barrier" may be completely broken by curvilinear (conical) 3D diffractive lenses with unique 3D super resolution (~0.4λ0 and ~0.8λ0 for transverse and axial respectively), but in contrast to the flat diffractive optic the curvilinear 3D diffractive conical optic allow to overcome 3D Abbe barrier with focal distance F more than F>2λ.
