Abstract

The paper describes the optical properties of the selected diffractive elements being promising for imaging with extended depth of focus. According to the results of our previous investigations, diffractive versions of the axicon and the light sword optical element were chosen for an analysis. Particularly we have examined the point spread functions of the above elements. The investigated optical properties of the selected diffractive structures were compared with the analogous properties of the conventional Fresnel lens. The results of the numerical simulations were verified experimentally in the optical set-up.
