Abstract

An experimental technique for controlling the statistical properties of a primary source by means of nematic 90°-twist liquid-crystal spatial light modulators (LC-SLMs) is proposed. The modulation of coherence and polarization is achieved through computer generated random signals applied to LC-SLMs placed at the opposite arms of an interferometric setup. Experimental results obtained by using Holoeye LC2002 modulators show the efficiency of the proposed technique.
