Paper Abstract

A method for performing optical beam shaping in the near-field region using diffractive optical elements generated by Fresnel based Phased Optimised General Error Diffusion algorithm (POGED) was developed and investigated by means of numerical simulations. POGED was found to deliver significantly higher signal to noise ratio than iterative Gerchberg-Saxton type algorithm.
