Paper Abstract

We present a design of diffractive phase elements (DPEs) that produce point/ring patterns based on the general theory of phase retrieval. The optical system is illuminated by monochromatic or dual-wavelength light. We carry out numerical simulations. The results show that the designed DPE's can satisfactorily generate monochromatic or color point/ring patterns with the given radii of rings in the above-mentioned illuminating systems. The color of the diffractive patterns can be arbitrarily altered. One of the designed DPE's was fabricated and its performance was measured. Experimental measurement is in good agreement with the numerical simulations. These DPE's suit for the applications in optical space communication.
