Vasylkovska I. Improvement of designing methods of diffractive lenses

The thesis is devoted to solving of a scientific problem of improving of designing methods of diffractive lenses with given optical characteristics. The properties of multi-order diffractive lenses are studied, the dependences of the image intensity on the design parameters of the lenses are determined. The methods of designing on the basis of the use of multi-order lenses for reduction of chromatic aberration and improvement of accommodation ability are substantiated and improved. The engineering methods of calculating of microrelief of multi-order diffractive lenses are developed. The method of calculating of multi-order diffractive lenses is improved. The method and the experimental stand for research of diffraction efficiency of a diffractive lens are developed.
