Abstract:   (934 Views)

In this paper we introduce a novel diffractive element which is generated by a given combination of a radially phase shifted Fresnel zone plate and grating. We show that the element has a great potential in generating a variety of array of annular beams with desired radius and distance. As well as, the annular beams may be generated in any form of array like rectangle or circle ones. The focusing properties of the element is explored, in detail by simulation. In addition, some experiments were arranged to verify the simulation results.

Keywords: Fresnel diffraction, Diffractive lens, annular beams, Beam shaping
