Paper Abstract

The design and fabrication of two binary phase diffractive optical elements is presented. We use iterative Fourier transform algorithms and a geometrical optics approach to design the diffractive elements. The outgoing beam shapes of the designed elements are compared by computer simulations. The advantages and disadvantages of each design are presented.
