Paper Abstract

A technique to obtain a diffractive laser beam splitter is presented in this paper. The technique is based on the approach of Fresnel holography, computer generated. Starting from the coding techniques used to obtain binary Fresnel encoded lens and Fresnel holograms, the synthesis of a diffractive optical element able to realize the split of a laser beam into N beams, is presented. Experimental results are provided for N equals 2, 3, 4, 5. The performance of this beam splitter is discussed in terms of light transmission efficiency and reconfigurability.
