Figuras de difracción en lentes holográficas

Abstract

Research on the imaging quality of holographic optical elements (HOEs) usually includes an evaluation of the wave aberration or calculation of the aberration spot using the ray tracing method. These methods, however, do not allow us to calculate the light intensity distribution in the image plane directly. Evaluation of the HOEs imaging quality is possible by using the diffraction theory of aberrations. By using the scalar diffraction theory and a simple numerical algorithm, we obtain the diffraction pattern for holographic lenses and a holographic lens with different reconstruction geometries has also been analyzed.
