Paper Abstract

Diffractive optics makes use of diffraction of light to design otpical elements and systems, which serve for imaging visual objects and transforming coherent optical beams. A diffractive structure can be computed and the pattern written using focused laser or electron beams. Phase nature of diffraction pattern is preferred. Computations involve the first and second order terms and a curvature of the substrate plate, which can be exploited for the element to be aplanatic. Diffraction grooves should have a suitable transversal saw-tooth profile to obtain the highest diffraction efficiency. An alternative method for fabrication of elements of this kind is holographic recording, which can be use mainly for off-axial components.
