• A diffractive optical elements (DOEs), permits to change a wave front by means of diffraction. The proposed method has the advantage of not requiring complex computation and programming. In particular the designed process is made without computer iterative methods. The DOE, implemented by the proposed algorithm, consists of cells of equal size. Each cell is subdivided into appropriate parts. The average phase of these parts is related to the phase of the complex amplitude. The DOE phase can be easily computed according to simple formulas. In the paper designing phases and numerical simulation are reported. In particular the effect of the DOE structure quantization is considered.
