Abstract

Some considerations on the design of computer generated phase elements applied to the intensity redistribution of Gaussian light beams are presented in this paper. The computer generated phase elements are designed using an iterative transform algorithm for Fresnel domain. Parameters which influence the performances of these algorithms and the computation time are discussed. Results obtained by computer simulations are presented for three different Gaussian beam shaping (flat-top, 2 shifted gaussians, acronym.)
