Abstract

A numerical and experimental comparison between different synthetic holographic codes is presented. Its performance is evaluated considering the generation of Bessel and Laguerre-Gaussian beams, as examples. Some reviews of computer generated holograms (CGHs) have been published in the literature but none of them have included a detailed comparison of their performance in the encoding of structured optical fields. The numerical evaluation includes an analysis of the theoretical features of each hologram and a calculation of Signal-to-Noise Ratio of the reconstructed field while the experimental evaluation assume the implementation of the holograms using a pixelated phase modulator.
