Modulation of coherence and polarization using nematic 90-twist liquid-crystal spatial light modulators

摘要

A technique for modulating the coherence and polarization of the electromagnetic field using 90o-twist liquid-crystal spatial light modulators (LC-SLMs) is proposed. The controlled change of the statistical properties of light is achieved through computer generated random signals applied to a pair of 90o-twist LC-SLMs arranged in an interferometric setup. Experimental results obtained using Holoeye LC2002 modulators show the efficiency of the proposed technique.
